After many years struggling with sluggish slow gtk4 (vs gtk3) and nothing helped, no fallback render, etc. (see my older posts), even on a very capable but about 10 years old GPU (Nvidia GTX 1070) on a i9 and i7 system. Simply a file chooser goes to a crawl… Now I upgraded to a modern AMD GPU Radeon RX9070 on the i9 (Gnome 48, Debian stable/Trixie 13) and RX9060 XT on the i7 machine (see details below). So that help general performance big time and gtk4 got super snappy – as a fact finding it sadly requires modern GPU hardware to be usable.
Fine.
With Debian Testing I now got forced to Wayland/Gnome (V50).
But I am running into a new very odd issue I was reading up on a though it was fixed with version 50, but obviously not.
My app is working initially, but once I open a few more windows at random I looses “mouse” control to them. I can move/resize them only using keyboard Option+Mouse/Mouse MMB. And most functions/button menus suddenly stop been functional also.
Google AI dug out this, I do not know much about it yet, but this about aligns with what I see.
Only I see it also on Gnome 50.
Any thoughts, hints, fixes?
