evolution_strange_border
SUMMARY
If I launch evolution (GTK email client which doesn't use the regular titlebar
and window buttons as most other apps) and configure the window rules to
forcefully make it use a titlebar, when it opens a subwindow to reply to an
email, it will add a titlebar to it, but along the way will add extra empty
transparent spacing throughout all 4 borders of the window (see attached
screenshot), which looks very weird, instead of just drawing the titlebar above
the usual subwindow without spacing in the way.
STEPS TO REPRODUCE
1. Launch evolution.
2. Right-click the titlebar and select 'More Actions' -> tick **off** 'No
Border' (alternatively, could be set to draw a titlebar in the window rules as
it's currently worded a bit differently there).
3. Configure evolution to access you email.
4. Select some random email inside evolution, right-click it, and select 'Reply
to Sender'.
5. Look at the borders in the newly opened subwindow.
OBSERVED RESULT
Has empty space extending across the borders, and there's a gap between the
GTK-drawn subwindow and the KDE-drawn titlebar.
EXPECTED RESULT
Should put a titlebar above the GTK-drawn subwindow, without extra spaces and
without having a gap between the window and the titlebar.
