Flatpak apps failing to launch on Wayland

General system Applications
1

Hi there, I recently updated my laptop and after reboot, flatpak applications suddenly failed to launch through the KDE application menu.
I tried to run flatseal through terminal instead:

$ flatpak run com.github.tchx84.Flatseal
MESA-INTEL: warning: ../src/intel/vulkan/anv_formats.c:763: FINISHME: support YUV colorspace with DRM format modifiers
MESA-INTEL: warning: ../src/intel/vulkan/anv_formats.c:794: FINISHME: support more multi-planar formats with DRM modifiers
Gdk-Message: 17:46:52.061: Error 71 (Protocol error) dispatching to Wayland display.

After reading this error message, I found the applications ran through X11 fine, but I would like it if they ran on Wayland again.

(Just in case this helps):

This is running fine for me in a gnome wayland session. You are running KDE. May be that is the issue.

PS
What kind of kernel is this 6.11.1-arch1-1.1-g14 ?

There is a thread with a similar error message in the arch forum:

https://bbs.archlinux.org/viewtopic.php?id=299546

It says: “After removing vulkan-intel the issue was solved. But why??”

Would this remove my iGPU from rendering things? I do use this laptop unplugged and don’t want to primarily use the dGPU for battery purposes

I dont know. I am not an expert on this. But in the arch forum they also say that

“Launching GNOME programs with GSK_RENDERER=ngl”

You can try that first.

This command does work to launch the application, but the issue is that scaling is comically incorrect, and I would prefer not to need to run things through terminal windows. So I tried running the applications using the LTS kernel as you suggested and found that it does launch without the need of an open terminal window. But the cursor becomes really large whenever you hover over or use flatpak applications.
