Hello,
I've been "lucky" again and found another machine behaving strangely
after updating to the latest xfce4 (4.16 on 12.2). I see two different
issues, but I cannot say if they're independent or not.
1. Some programs take very long until they actually start and open up a
visible window. Once the program runs, more of the same windows open up
quickly. I've seen this issue most notably with xscreensaver. After
typing the name in a terminal or clicking on the item in the start
menu, it takes about *1* *minute* until the window opens up. This feels
like there is some timeout involved, but I cannot get any error message.
2. Some programs don't show a "highlight" for the menu item the mouse
pointer is currently set to. The menues still work as expected, but you
don't see what entry is actually selected. Concerned programs are
claws-mail and lxterminal.
If there should be a single root cause: all affected software appears
to still use gtk2, so maybe the issue is buried somewhere there? Is
there an easy way to reset gtk2 settings (while keeping everything
else)?
First I thought that xfce4-terminal might also be affected as it took
ages to re-open my saved session. However, maybe it is just trying to
start something else before, and that is blocking everything else. Menu
highlighting definitely works fine for it.
Any hints are greatly appreciated.
XFCE itself removed all support for gtk 2. But maybe after upgrading you
still have some gtk theme? try grepping your packages for "engine" and
"gtk", most probably you can just remove any gtk theme/engine you find.
Pay caution anyway, obviously.
Also check in ~/.config/gtk-2.0 if you have any custom configurations there.
I can't remember the systemwide gtk customization files location, but
I'd look into:
/usr/local/share/gtk-2.0
/usr/local/share/gtk-engines
