Hmm. If change the shadow quality to high and restart, does the problem happen? Also if switch to Very High after a start with High does the problem happen? Also could you add the following line to your user.cfg? renderer.backend.vulkan.disabledescriptorindexing = "true"  

Yes it still happens when all other settings are disabled. Here's the log with the flags you gave.    mainlog.html userreport_hwdetect.txt

Could you add the following lines to your user.cfg (might be removed later) and attach mainlog.html and userreport_hwdetect.txt after run with it? renderer.backend.debugcontext = "true" renderer.backend.debugmessages = "true" renderer.backend.debuglabels = "true" renderer.backend.debugscopedlabels = "true" Also is the problem reproducible when all other settings are disabled?
