Sway used to have an issue where unmapping a subsurface did not damage
the surface below (https://github.com/swaywm/sway/issues/6960).
This has been fixed for quite some time now, so let's remove the
quirk.
When unmapping a sub-surface, Sway <= 1.8 does not damage the surface
beneath the sub-surface.
https://github.com/swaywm/sway/issues/6960
The workaround is to manually damage the main surface. Previously,
this was done when exiting scrollback search, and after the ‘flash’
OSC. But other sub-surfaces, that may also be unmapped, did not.
This patch adds a quirk handler that does this, and calls it when:
* Exiting scrollback search
* Ending the ‘flash’ OSC
* Exiting unicode input mode
* Clearing URL labels
* Removing the scrollback position indicator
Closes#1335
Older version of Plasma/KWin had an issue where buffer damage recorded
before the buffer was attached were ignored. This appears to have been
fixed now.
KDE resets all surface damage when a buffer is attached. Add a quirk
that adds a full-buffer damage to the surface. This quirk is intended
to be called after attaching a buffer to a surface.
