Version: 4.18.0-1
Severity: normal
X-Debbugs-Cc: betaver...@gmail.com

Dear Maintainer,

after updating xfwm4 from 4.16.1-1 to 4.18.0-1 taskbar now is always visible,
when using borderless fullscreen, like when watching video fullscreen in MPV or
on youtube in browser, or playing games with borderless fullscreen. If game
uses exclusive fullscreen, taskbar is not visible.

I tried using Openbox instead of xfwm4 and with Openbox taskbar works as
expected: not visible in borderless fullsreen.

DE is LXQt.

Hi, thanks for the report. Along with #1026884 it seems with have some
behavior changes regarding struts (reserved spaces). I'll try to ping upstream
about that.

Hi, so I just checked locally and I can't reproduce, at least when using mpv
and using F it correctly cover the whole screen; same with Firefox and a
youtube video. Could you elaborate a bit on what exactly you're doing?

Hi. This problem has already been solved by updating lxqt-panel to 1.2.1-1. So if you have lxqt-panel 1.2.1-1 installed, I guess you won't be able to reproduce this bug. Anyway, the problem is solved and this bugreport can be closed. Thank you for your time.
