Dear Maintainer,

Since installing the new version on sid gtk4 applications crash on
startup with SIGSEGV.

The crash seems to occur with the vulkan renderer, disabling it with
GDK_DISABLE=vulkan things run fine.

I'm running a kde desktop on wayland (kwin-wayland 4:5.27.11-2)
on AMD with mesa-vulkan-drivers 24.2.2-1

Example partial backtrace:

Thread 1 "zenity" received signal SIGSEGV, Segmentation fault.

I can confirm this issue and filed this upstream.

As additional info: the segfault does not happen for me when I run those applications from within a GNOME desktop session. My backtrace looks slightly different though, maybe a result of having fractional scaling enabled (150% for the external and internal monitor). @Simon: If you think we should split this into two separate bug reports, please let me know.
