Bug#987886: krita: Right-clicking on the canvas crashes krita
> I tried to reproduce this issue inside a virtual machine.
> But there the menu opens without the issue.
I can reliably reproduce this in Debian Bullseye; it appears like the
environment variable QT_SCALE_FACTOR needs to be set to a non-integer value
(which is supported!) for the crash to happen. By default I'm using
QT_SCALE_FACTOR=1.7 and it crashes — it doesn't crash with QT_SCALE_FACTOR=1
or QT_SCALE_FACTOR=2.
Testing inside a Sid+Experimental chroot, version 5.0.0~beta1+dfsg-1
from experimental seems not affected.

It happens with only a keyboard and a mouse as input devices attached.

It just crashes without any dialog, even with MALLOC_CHECK_=3 and
I'm afraid I don't know which smiley or clock you're referring to.
Before right-clicking and crashing the console log already shows a bunch of
warnings like these, which might or might not be related to the crash:
QImage::setPixel: coordinate (132,166) out of range
QImage::setPixel: coordinate (133,166) out of range
QImage::setPixel: coordinate (134,166) out of range
QImage::setPixel: coordinate (135,166) out of range
QImage::setPixel: coordinate (136,166) out of range
To get more info I ran krita in gdb, with
set args --new-image RGBA,U8,1600,1600
set environment MALLOC_CHECK_ 3
set environment QT_SCALE_FACTOR 1.7
run
On right click, gdb first showed the following:
Thread 1 "krita" received signal SIGABRT, Aborted.
__GI_raise (sig=sig@entry=6) at ../sysdeps/unix/sysv/linux/raise.c:50
50 ../sysdeps/unix/sysv/linux/raise.c: file or directory not found
Then I requested the backtrace, whose entirety can be found a few lines below.
I hope this helps in locating and fixing the issue (and backporting the fix to
Bullseye). If you need any more information or something tested I'd be happy
to help.
Cheers
