I have a 3D printing software that does not display well on Wayland. Instead of relogging to start a x11 session is there a way to force that one software to display in x11 instead of Wayland?
Edit
AddingQT_QPA_PLATFORM=xcb to the enviroment variables was the solution for me.
Thanks to everyone for the help.
Additionally once you figure out the environment variable you can add in to the .desktop file so it will launch from a launcher in that way, though updates will reset that.
On arch wiki is a page on wayland which includes info on toolkits, though you may need to figure out the x11 option it will include the variable/option needed. https://wiki.archlinux.org/title/wayland#GUI_libraries
Copy the .desktop file from root (/usr/share/applications) to the local directory (~/.local/share/applications), then your package manger won’t overwrite your changes
