Continuously scrolling the middle mouse button in the material blueprint interface of UE5.5.1 will definitely crash.
Does anyone have the same problem?
Hey there @jysirius! I can’t seem to replicate the issue myself. Does it crash during basic scrolling or when it maxes out or randomly at some point? May I know your OS? (And if on Linux your window manager as well).
The OS is Windows11.
It’s random crash.
I found that the interface would get too laggy when scrolling the middle key.
But another UE project won’t have this crash, I’m confused.
Does this still occur on empty materials? May I see the crash context itself?
I found that when I delete some nodes, it doesn’t crash anymore. And no matter what node is deleted, it can be done. Perhaps it’s because there are too many nodes?
Before deletion：
After deletion：
It seems like it’s GPU side memory is going out of context. Are there any materials using this function at the moment? This in and of itself isn’t that large of a material function, though I can’t quite see how complex the nodes are from such a distance.
Currently in use and very stable in version 5.4, only crashes after upgrading to 5.5.
Using a 4090 graphics card and the latest drivers.
Ahhh, interesting! Definitely seems like 5.5 updates may have caused either some higher overhead or another bug. Does the crash still occur if running in DX11? (This is just to test if it’s overhead or something else).
I tested it and it won’t crash in DX 11, The interface is very smooth
That narrows it down a bit to either some DX12 only feature that had been changed or massive overhead change in memory with the version. Are your Nvidia 3D settings currently default?
Yes, it’s the default setting
