Mouse input blocked in Wayland KDE Plasma 5

Open nitrogar opened this issue 5 months ago • 10 comments

Describe the bug I am using Manjaro in Wayland with two monitor setup, and when i start gromit the screen freezes until i kill gromit. the problem does not happen on xorg only Wayland.

I would like to help in finding the bug more precisely but i don't know how to debug it since it freezes the screen upon launch

but I noticed that not all the desktop environment are frozen I can spawn terminal using short-cut but the mouse pointer disappear and i cant interact with any opened window

OK, can repro on KDE Wayland Manjaro using Gromit-MPX flatpak.

Seems like a Plasma bug/feature w.r.t https://docs.gtk.org/gtk3/method.Widget.input_shape_combine_region.html - maybe upgrading to Plasma 6 might help?

I encountered the same issue on Plasma 6 Wayland too. Gromit tray icon does not even respond to mouse clicks. Atl+F9 also does not kill gromit, not fix the issue either.

Hmm works in GNOME Wayland. Could someone open a report at upstream KDE and link this here? I can provide technical details then.

Investigate #136

@lmtreser thanks a lot! If you're fit in C coding, what would help is a minimal gtk-based program to reproduce the issue for upstream KDE that creates a simple window that via gtk_widget_input_shape_combine_region() is transparent to input (lets clicks though) on KDE X11 but not KDE Wayland. This basically is what Gromit-MPX does.

Hello! When updating Kubuntu to 24.04 LTS, several things that didn't work are now OK... For example Gromit. Solved!

@lmtreser can you post your exact KDE version for us please?

I rushed to post this message, because I just realized that by default Kubuntu 24.04 starts the session in X11 and not in Wayland... The problem persists on the Wayland session 😔.
