Frequent Crashing and Multiple D3D11RHI (DirectX11) and DirectX12 Errors after Windows 10 May 2020 Update (2004)

Development Programming & Scripting
1

I am getting DirectX11 errors since performing the Windows 10 May 2020 Update (2004). Unreal Editor was working fine prior to the update… and ever since it has been completely unusable due to what are seemingly DirectX 11 RHI errors. Even when using DirectX12 SM5 only, I am getting frequent hangs… usually not when flying about in the 3D viewport, but when hovering over or clicking on icons and fields in the editor.

I have updated drivers, tried increasing the TdrDelay in the registry, used DDU to clean drivers out entirely and update them to Windows 10 2004 compatible drivers… I’ve updated to Unreal Engine 4.25.2… I’m out of ideas

Does anybody have a fix?

The first error and crash report I received:

ERROR 1:

ERROR CONTINUING:

Now, after having changed the settings to only invoke DirectX 12, SM5: only D3D12RHI appears in the console output and the logs… and I never manage to get a crash report. However, Unreal Editor is still frequently crashing. For the most part, flying around in the viewport is fine… it’s only when I’m hovering over editor buttons, or clicking on fields that the editor hangs…

An interesting quirk is that if I press the hardware sleep button on my computer, and then immediately log in again, the editor is working again. It crashes pretty immediately thereafter, but the sleep trick works every time.

Strangely, when I tried to screen capture a video, I was unable to reproduce the error, as perhaps the overlay (Gyazo GIF) was stopping the crash from occurring?

Sorry to disappoint but I do not have any answers to this, but I did want to let you know you aren’t the only one dealing with these issues. I myself have been getting constant D3D11RHI errors which crash UE4. I myself reported this but have gotten zero answers to my issues. I hope someone answers one of us soon for our sake. Good luck to you!

Hi, I’ve been having the exact same (or so it seems) issue for a while now.
On my end the crashes seem to stop if I turn off “automatically hide the taskbar in desktop mode”.

Keep in mind though, I’ve been trying to fix the issues for weeks on end and can’t guarantee it was only this setting that did the trick.

I don’t understand how or why, but it seems to work for me, so I figured it was worth sharing.

PS. If it still hangs, windows+ctrl+■■■■+B restarts your gpu drivers, this helps from time to time.
Also, if you use multiple monitors, unreal seems to behave differently depending on which monitor is set as main in your windows settings. (I’m still experimenting with how this affects everything)

PPS. Which monitor is set as main only seems to matter if you don’t show the taskbar on all displays. In short, the crashes seem to be fixed as long as unreal is either not fullscreen, or is fullscreen with a visible taskbar

By the way, has anybody managed to successfully upload a bug report? For me the web form doesn’t even allow me to submit…

5

So, I have actually managed to hunt this issue down to an error around the interaction between Intel Drivers and/or Desktop Window Manager.

EDIT: I have written up a summary as an answer below, instead of a comment…

So, I have actually managed to hunt this issue down to an error around the interaction between Intel Drivers and/or Desktop Window Manager.

The same type of application hang appears to be happening in both Blender and Unreal Engine.

With Blender, after a while of zooming around the 3D viewport, sporadically, the application appears to hang. If I check the Windows Event Manager and Reliability Monitor, I notice a hardware error, an igfxn driver error with Event ID 4101:

‘Display driver igfxn stopped responding and has successfully recovered.’

leading to a drop out and then recovery of the drivers… but then with Blender, even after the drivers have recovered, the window thereafter fails to update (you only get one hang before it becomes unusable), while the application is still running in the background. The application window no longer updates (even with your awesome ‘Windows Key + Ctrl + Shift + B’ driver reset hotkey). I can, however, still save the file, as I can see that the * denoting unsaved changes in the title bar still updates… and then exit the application. I can even perform operations while the application window is hung… I have to exit blender and restart to be able to continue. It happens about 20s to 3 min into using the application usually.

In Unreal, I have similar issues which are documented here… when the application window hangs, operations can still occur, but in this case, resetting the drivers with the hotkey combination does reset the window and allow me to continue. The application typically hangs while hovering over text elements and fields, and not while e.g. simulating the game in the 3D viewport (which would seem to be more graphically intensive).

Various other error reports have promoted fixes including setting TDRDelay, or making sure the window is not maximised etc…

Seemingly… Desktop Window Manager/Intel interaction… In Event Viewer, the issues appear to be of type 0 or 5, WindowsBlackScreenDiagnosticsV1 or LiveKernelEvent / hardware errors. Maybe one of those is an event to log the hotkey press… but nevertheless, Reliability Monitor shows me hardware errors preceding any of these hangs.

For Blender, we have Hardware Errors with LiveKernelEvent code 141
For Unreal, we have Hardware Errors with LiveKernelEvent code 1a8

Also, not sure where 1KawaiiTomato’s response went, but this post was valuable and has since disappeared:

ah… must have been a cache problem

If you are experiencing similar errors, please upvote this Feedback via Windows Feedback Hub, so it can get some engineer and developer attention from Microsoft. I have also submitted feedback to Intel Support:

10

I disabled the automatic hide taskbar function and UE4 editor works again for me as well.

11

WOW! This may have just solved it for me… I will update the Windows and Intel Support on this

12

Please upvote this issue here in the Answer Hub (top-left of the OP Topic), and on the Microsoft Feedback Hub thread so we can get some dev support from Microsoft to relegate this to a non-issue:

13

i had the same problem here. What i found is that when using dynamic material instances, if you have different instances of the dynamic instance material, both created from the same parent but have THE SAME NAME, it will certainly crash D3D11RHI. Creating a unique name for the entire project solved the problem for me. I created an integer variable in player controller and increment the number on every new material that I created.

Note, Windows just installed new updates which once again seems to have enabled auto-hide the taskbar, and the error re-appeared. This is also with a new setup, using a powerful egpu (graphics card is not the problem). Fixed by disabling auto-hide the taskbar.

Found this as well. The cross-links show that this issue goes way back to the release of a 4.12 or 4.13 version of UE4 Editor… which is not so coincidentally the same time around which D3DRHI errors started occurring in many other bug reports related to D3DRHI device ‘lost’ errors and such: here, here, here, here and more recently, here and here.

This thread here seems to be very current, and the same issue as we are experiencing. I would highly recommend following it and posting in here!!

In recent news, I totally rebuilt my machine and reinstalled windows 10 with a clean install, and got an eGPU with a GTX Titan Xp, so I’m now using more than just Intel i7-1065G7’s integrated graphics. The problem still persists when auto-hide the taskbar is on.

Also, recently, I was running Assassin’s Creed Odyssey’s menu screen, but alt-tabbed to the background, and it disrupted some window overlays in e.g. Blender, and the sounds from hovering the cursor over menu buttons was occurring in all other applications.

I am convinced that there is an issue in the combination of Desktop Window Manager being faulty, and the way in which Unreal Engine implements it in general. The problem seems to have been around for a while. What is getting in the way of a fix??

Actually realised that when I alt-tab, indeed Assassin’s Creed is still running in the background and the window overlay issue is present. However, if I four-finger-swipe to ‘Switch Desktops/Show Desktop’ as per windows settings, Assassin’s Creed actually minimises.

Update: Auto-hide the taskbar doesn’t seem to crash the editor EVERY time, when I have the eGPU plugged in. However, there is a problem when I have HDR setting turned on in Windows settings, with the eGPU plugged in. Unreal crashed with D3D11RHI error whenever I clicked a menu button, or even ‘x’ in the top right corner to close Unreal Editor.

Is this related to fix UE-88616?

Also issue UE-57821?
