This issue aims to list all the issues you might encounter because of Wayland, and potential workarounds, if any. This ArchLinux setup uses sway which is based on wlroots. I will try to keep it as up to date as possible, you can of course contribute.

Gimp

Gimp 2.10.x uses GTK2 which requires X11. Therefore Gimp is not usable yet under Wayland.

Workarounds:

• Install gimp-devel from the AUR (unstable)
• Wait for Gimp 3.0 to come out

Flameshot

By far my favorite screenshot utility is broken right now on Wayland.

In the meantime I use slurp + grim + wl-copy.

I have the following in my Sway config file:

bindsym Print exec grim -g "$(slurp)" - | wl-copy
