This happens at least=20 on Emacs and Firefox (I admit I haven't tested on IceCat), happens=20 in both Sway and Gnome on Wayland, and does not happen in Gnome on=20 X11. Which makes me think it is related to XWayland. On Emacs, some select letters (often 'o') are not rendered. Parts=20 of the windows are not refreshed when other parts are updated.=20 Logging out (to SDDM) and back in fixes the issue. Has anyone been experiencing this? I'm not sure how to start=20 troubleshooting, or what channels to use to explore this. Any help=20 will be much appreciated! Best, S=C3=A9bastien
