Just upgraded to F35 on a gnome wayland session (with the nouveau driver), and its getting the Xwayland root window size wrong. I have 2 3840x2160 monitors, with the left one in portrait mode and the right in landscape, so the root window should be 6000x3840, but xwininfo -root says: Width: 7680 Height: 2160 Seems like its not taking orientation into account.
Note, this is not just a cosmetic issue, as it doesn't allow mouse events outside the root window size.
wayland-info says: interface: 'wl_output', version: 2, name: 4 x: 2160, y: 757, scale: 2, physical_width: 600 mm, physical_height: 340 mm, make: 'AOC', model: 'AG271UG', subpixel_orientation: unknown, output_transform: normal, mode: width: 3840 px, height: 2160 px, refresh: 59.996 Hz, flags: current preferred interface: 'wl_output', version: 2, name: 5 x: 0, y: 0, scale: 2, physical_width: 340 mm, physical_height: 600 mm, make: 'AOC', model: 'AG271UG', subpixel_orientation: unknown, output_transform: normal, mode: width: 2160 px, height: 3840 px, refresh: 59.996 Hz, flags: current preferred interface: 'zxdg_output_manager_v1', version: 3, name: 6 xdg_output_v1 output: 4 name: 'DP-1' description: 'AOC 27"' logical_x: 2160, logical_y: 757 logical_width: 3840, logical_height: 2160 xdg_output_v1 output: 5 name: 'DP-2' description: 'AOC 27"' logical_x: 0, logical_y: 0 logical_width: 2160, logical_height: 3840
As noted by oliver, this only happens when i change the orientation live during the session. It works right if the orientation is set at login.
Eh, olivier
This is because of https://gitlab.freedesktop.org/xorg/xserver/-/merge_requests/492/diffs?commit_id=da791ed9f Reverting that commit fixes the issue. The only thing is that commit is already a revert, which itself was a revert of another commit… https://gitlab.freedesktop.org/xorg/xserver/-/commit/da791ed9f reverts https://gitlab.freedesktop.org/xorg/xserver/-/commit/427f8bc00 which reverts https://gitlab.freedesktop.org/xorg/xserver/-/commit/a05453266 and https://gitlab.freedesktop.org/xorg/xserver/-/commit/ce2dde9e so we may have some discrepancy between compositors here…
I suspect this might a be a regression in mutter GNOME 41, the same seems to work fine in GNOME 40 on Fedora 34.
Confirmed, this is a regression in GNOME 41, moving to mutter.
