Re: Krita 6 not working after update

It was a full system upgrade. In fact, I had ran -Syu yesterday because I thought krita 5.3 had released and it was fine, I then ran -Syu again today, which caused the problem. I rebooted my system

Re: Krita 6 not working after update

I recompiled mangowm and rebooted without success. I've uninstalled qt6ct trying to narrow down the problem, but it just had stopped applying the theme, e.g. dolphin, qbittorent. I've also tried to unset QT_QPA_PLATFORM and QT_QPA_PLATFORMTHEME. This person had the same problem on the same update, but  for another program https://github.com/AyuGram/AyuGramDesktop/issues/314

That's the full Krita log

Re: Krita 6 not working after update

I've also tried the 5.3.0 AppImage version and it works fine.

Re: Krita 6 not working after update

Is that https://wiki.archlinux.org/title/Waylan … plications ?

I'm on Mangowm Wayland session

Same on eg. weston?

Do you also have a backtrace and shell output for qt6ct?

Re: Krita 6 not working after update

qt6ct opens fine, but it was functionally useless as it wasn't applying the theme. I've reinstalled it with -Syu and rebooted, and now it's applying the theme but not the colors. which were working previously, but I guess that's just the usual "theming QT outside of KDE" nightmare.

The problem is krita crashing.

Re: Krita 6 not working after update

I just installed weston to test, and it gives me a different error, but I think it`s unrelated, it seems to be trying to run it through xwayland

$ krita
qt.qpa.xcb: could not connect to display 
qt.qpa.plugin: From 6.5.0, xcb-cursor0 or libxcb-cursor0 is needed to load the Q
t xcb platform plugin.
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it 
was found.
This application failed to start because no Qt platform plugin could be initiali
zed. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, 
vkkhrdisplay, vnc, wayland-brcm, wayland-egl, wayland, xcb.

Thanks, TIL krita ships its own platform plugin. Should be fixed in 6.0.0-2.
