Package: xfce4-panel
Version: 4.18.2-1
Severity: normal
Dear Maintainer,
after upgrading to xfce4-panel from bookworm, the workspace switcher has
become unusably large (wider than my screen).
after realising this is not configurable, I dug a bit into the code and
found that plugin->ratio is set to 7.1, which explains why the switcher
displays extremely elongated miniature views - it apparently assumes my
display has an aspect ratio of 7.1, when it actually has a ratio of 1.78
(standard full hd).
I found that the ratio is calculated differently in bookworm's panel:
before, it was screen width / screen height (which is 1.777.. on
my system). Now it takes the workspace width divided by workspace
height. Since my workspace is 8x2 screens in size, this results in 15360 / 2160,
or 7.1.
So it seems to apply the full workspace aspect ratio as if it were a
single screen inside the workspace.
I think either the ratio calculation is wrong, or some other code uses
this in the wrong way (workspace vs. single screen).

thank you for your report, but I'm not sure I understand and/or
can reproduce it.
Using a fairly standard Bookworm install with Xfce, the workspace switch
seems just fine for me. I tried to configure the plugin to display using
two rows, then added 16 workspaces (to get a 8x2 layout like you) but it
seems to display just fine.
Could you take a screenshot or something to help us investigate?
Regards,

Hello,
There is a problem. It is very easy to reproduce it. Just install compiz and specify Desktop size => Horizontal Virtual Size = 4 (for example). After that, add the Workspace Switcher applet. After that, each cell of the desktop will be equal to the virtual size.
