AMD users : Latest AMD driver released today 26.1.1 fixes Lumen HWRT causing crashes in Editor
I have tested it in 5.7.2 with RX 9070 XT and can confirm the driver fixed crashes at editor startup when enabled.
everything nice but i feel i have started experience my 14700kf degradation. It behaves in compile in VS2026.
So everyone get memory adress error while compiling Engine (CL.exe)- it is error that comes from instability of CPU in my case. - It can miss crucial DLL so engine will work partially till something will be needed. Or it behaves some sort of dlls not is licensed for windows sort of when starting.
ive reduced undervolt and get one error but still trying to avoid
So trying to compile without this error and make a backup. Do not trust Intel settings even after BIOS updates. So on my Z790 UD AX voltage offset from -1,2 went to -0,85 and seems like Helped also protect voltage peaks to 1,35 to be sure slowing down computer but wish that CPU not brick . 
For someone who is solo and wont change to Rider . VS 2026 cool fill and predict code also.
Seems this is not resolved in 5.7.2 
Also about some Dirt in WP. I have here clock that synchronize movement of the objects after reaching tile first time everything well. After leaving and going back its not cleared proper so forcing Garbage collecting is required for moving actors between cells. For that 25 FPS target i recommend 0,5 second (5.7.2) project from 5.7 - will try to make fresh project with wp and move code there to see if that is not the case.
EDIT: Fresh Project same so cleaning service must run in loop on the map atm for moving platforms etc.
Nanite + Landscape, RVT + WPO still broken in 5.7.2 : Is Nanite Tessellation broken on terrain in 5.6 ?
Text3D got some fixes in 5.7.2 - I had to remove it all from my project because I couldn’t trust it anymore and it was tied to my scoring system. I already wasted enough time trying to make it work but curious if others who were using it before when it was working can test it out. My biggest issue was all the BP controls broke - Also not being able to control the collision on the spawned text had the player bouncing off it every time it spawned. My new system uses the 3dText Plug as a modeling tool to generate static meshes and then I created a system that uses static meshes to spawn the right number for the right scoring value it works fine just a pain in the ■■■ if I want to change a scoring value.
Suggestion: When the editor is running display a notification when a new version goes live.
5.7.2, widget connect to Set Style node will crash.
Until an official fix being provided, this command line fixed the rounded Background Blur not showing in the packaged build problem:
Microsoft just flag Source as an risk. Had to disable intelligent app protectiom to run it.
Maybe this is a bug in 5.7.2
After using the Localization Dashboard - Gathering once and or editing text, gathering or compiling seems to always fail with the following message: LogLiveCoding: Display: Waiting for server
And there is a UnrealEngine process running and not always shutting down on its own, and this is why above error is displayed.
Fix: restart the editor and end the running UnrealEngine task. If this doesn’t work restart the OS.
Also that “dirt” in WorldParition causes issues with actors that are placed in the world.
as example overlap function is called twice.
Begin Play
OverlapBox->OnComponentBeginOverlap.AddDynamic(this, &ABoxActor::OnBoxBeginOverlap);
So each instance need to be unique to resolve pretty huge spike (AddUniqueDynamic) or cleaning garbage as often as possible
Upgraded project from 5.6 and something fishy is going on with Retain+Invalidation boxes…I had to add Slate.InvalidationRoot.VerifyCachedElementDataList=1 otherwise crash crash crash.

I found an in blueprint workaround by using the Set Members In Editable Text Box Style node. It’s stupid but prevents crashes for me. 
Thank you for sharing this. It’s been driving me crazy 
Mother of*, hotfix in 3 weeks, wow. Just like 5.6 only get one 
Is anyone else failing to build the latest release from source? It’s failing because it’s got references towards the restricted libraries I think? Time for another hotfix? Happens when running the development editor in visual studio 2022 community
edit - removing the build configuration for the tests works by the way. I’m back up/running after doing so.
I could be wrong but I think you switch it on in settings and it automatically converts. At least it seemed to have better performance when I did
