Update of libwnck3 from 3.36.0-1 to 40.0-1 breaks mate-panel 1.24.2-1 workspace switcher aspect ratio. Displays with 16:9 aspect ratios appear as 1:1 in the workspace switcher applet.


Reverting from libwnck3 40.0-1 back to 3.36.0-1 restores proper aspect ratio in the applet.

Reported to upstream.

Update of libwnck3 from 40.1-1 to 43.0-2 brakes mate-panel 1.26.2-1 workspace switcher aspect ratio (again). This appears to be the same bug/incompatibility between mate-panel and libwnck3 that this bug report had initially identified. The incompatible code in libwnck3 40.0-1 that triggers this bug was *temporarily* reverted back to the code in 3.36.0-1 by the libwnck3 devs to avoid the bug and give the mate-panel devs time to update their code.


40.1 was released with revert - https://gitlab.gnome.org/GNOME/libwnck/-/commit/7fab141ba787cecb576b732c9182b006453d82f4.

Note that mate-panel still needs to be fixed for future libwnck releases!

Apparently after 8 months, libwnck3 has moved on and been updated such that mate-panel is again incompatible with libwnck3. The mate-panel devs need to fix their code if they want to continue using libwnck3 as a dependency. Reverting the Arch libwnck3 package back from 43.0-2 to 40.1-1 will again avoid this bug, but eventually a permanent fix in mate-panel is needed.
