Problem solved, a white icon background but it moves perfectly! > It would also be interesting to test under a Wayland session No issues at all under Wayland. Just perfect! So I guess I will use Wayland for now... The problem seems to be in the compositor under X11. If you need more info about my setup, just tell me. Thank you all!
