Can anybody interpret this for me and give me an idea of how I might address this:

Thread 1 "krita" received signal SIGSEGV, Segmentation fault.
0x00007ffff638fa30 in QOpenGLFramebufferObject::handle() const ()
from /usr/lib/libQt5Gui.so.5

This happens after I open Krita and try to create a new document.

Let me know if I need to provide any additional info.

Any assistance is greatly appreciated. Thx

I'm guessing you're using the krita appimages? Which version exactly? Which Linux distribution? Which version? Which graphics card and if nvidia or amd, open source or proprietary driver?

The easy workaround, of course, is to disable opengl before creating a document, but that won't help us figure out what's going on here.

Version 3.0 Alpha - git d37d252
Antergos
Integrated Intel graphics using i915

Thanks for assistance!

Did you build Krita yourself? If so, could you build with build-type RelWithDebInfo and see what the full backtrace is?

Not sure if its the same, but I just used gdb bt. Here's what I got:

No... That still doesn't have any useful information it; no debug symbols and the entire backtrace is in Qt, not Krita.

Unfortunately, I'm not having any luck building it now. I had been using the AUR git version, which I tried to build again with RelWithDebInfo, but no joy. same with the other versions I've found. Not sure what the issue is.
