I tried playing Minetest through Zorin Desktop in Wayland and I noticed that on screenshots the taskbar appears despite I never really moved the cursor on the lower screen border to make it appear for the screenshot.
Time to return to X11 then, I don't want to see the taskbar on my screenshot if not intentional . Do you think I can report this thing on their GitLab page? Perhaps for me it's harder to know on which component the issue depends on, because for example I play 3D games so they probably use Mesa 3D but I can't know for sure if the issue depends on Wayland, Mesa 3D or the game environment . In this case with the taskbar I was more likely to think to Wayland rather than Minetest environment since this issue happened right after switching to Wayland.
