--- Comment #2 from Matt Fagnani <matt.fagn...@bell.net> ---
I saw this type of crash when clicking on Konsole and Dolphin's icons in the
task manager as they were running and the wallpaper was shown and disappeared
so that those programs were shown, so the wallpaper might not be the image
being processed in the trace. The texture image might be related to the
animation of the window expanding or shrinking when the program was maximized
or minimized in front of the wallpaper. I didn't see the problem when clicking
on the task manager icons of one of two maximized programs, and that animation
didn't appear when I did so. I didn't notice this problem with the radeonsi and
amdgpu drivers on bare metal and llvmpipe and virtio-gpu drivers in VMs, so the
problem might be specific to virgl.
I reproduced the program in nested kwin_wayland under valgrind by clicking on
the Konsole icon in the task manager a few times. There were many conditional
jumps or moves depending on uninitialized values involving kwin and mesa which
might have resulted in undefined behaviour and memory corruption. An invalid
read in convert_ubyte_rgba_to_bgra (format_utils.c:219) with an access not
within the mapped region at address 0x3BDEC000 was where the segmentation fault
happened.
