Hi, At the weekend I updated my system and after reboot some of my apps have lots of black black squares/rectangles all over the place, covering all of the app window and making email difficult to write.
Initially I thought this was a Wayland problem as using Wayfire but switched to X11 desktop and still had same issue. Trying all my apps this looks to be a GTK related issues as happening with claws-mail (worst), gkrellm, gcolor2, Bluefish etc. QT/EFL apps seem to be fine (qtfm, keepass). Firefox-bin works just fine, oddly. Anyone else seen this. I see a thread talking about GTK slots but not sure if this is related. I've rebuilt all gtk related packages which has not helped. John
