• Transparency effects in Xfce4

    From Markus Robert Kessler@2:250/1 to All on Sat Mar 11 18:18:57 2023
    Hello everyone!

    In desktops like Xfce4 or Gnome you can make use of composite /
    transparency effects. These still work in today's versions, but if
    activated, they cause severe trouble during screen recording and desktop sharing (Jitsi, Teams etc.).

    Someone created a bug report, see here

    https://bugs.mageia.org/show_bug.cgi?id=29405

    Does anybody know which component / package is responsible for
    transparent window frames, panels etc.?

    So, one could try to fix the issue, since it once worked (in MGA6 it was
    ok, but from MGA7 on trouble started).

    Thanks!

    Best regards,

    Markus

    Each desktop environment that has it implements transparency in it's own packages.
    There is no shared lib that handles it for them.

    What ever has changed it's up to the recording software to handle, or at least document that it should be disabled. It may be changes in the recording software
    that has caused the issue rather then changes in how transparency is implemented.

    So, the malfunction in xfce4 and in kde/plasma are two different things, happening at the same time.

    Well, in the case of xfce4 I now installed compton as a replacement, and
    it can be easily started automatically by just activating the checkbox
    for compton in xfce4's autostart section, and, xfce4's built-in composite engine can be deactivated.

    This works as expected, except that this solution is terribly slow when dragging around windows on the desktop.

    In many forums this has been discussed, but people can only guess, why
    this occurs, but there seems to be no solution.

    Is there any other compositor, which can be loaded instead in xfce4?

    Best regards,

    Markus

    I normally disable composting as I find it annoying. I'm not aware of what options there are other then the defaults.
