--- Comment #4 from gudvinr+...@gmail.com --- (In reply to Filip from comment #2) > Can you open Display & Monitor section in System Settings and check the > orientation setting for your monitor? Switch it to vertical. It is switched to vertical (and was before too). (In reply to Filip from comment #2) > Is this your first boot or was it working before and got switched to > horizontal? Not the first. It's working system that I use on a regular basis. It's not switched to horizontal, it is vertical. But wallpaper and some other stuff (like box selection) thinks it's horizontal.

Does any of this happen if you log into a Wayland session on the same > machine? Or does it only happen in an X11 session? 1. Don't really understand the question. I see what's shown on screenshot. Top part shows wallpaper, bottom part is black. 2. No 3. Yes, it does 4. Can't say, don't use wayland as it has issues more severe than this one -- You are receiving this mail because: You are watching all bug changes.
