I’m using Unreal Engine 4.26.2, stock, on Windows 10 Pro, on a 128 GB machine with a NVIDIA RTX 3090 running drivers version 471.11, connected to two 1440p displays.
Every hour or two of using Unreal Editor, the editor provokes the system into “D3D Device Lost” (the hard part, where it resets the desktop, restarts the monitor links, makes Photoshop crash, etc.)
Why am I picking on UE editor? No other program causes this to happen, although I realize that, theoretically, the driver should never allow this in the first place. Several programs do misbehave after it happens, not just Photoshop. Youtube Music Desktop, Slack, and a few other programs also tend to misbehave after device lost, presumably because the Chromium rendering engine they use has some problem with that, because device lost is intended to be “uncommon” these days …
Is there some known resource leak that can be patched? Is there something I can do to debug this? (I will try the latest Studio drivers, because apparently there’s a newer version now.)
