Title:
window redraw glitches caused by ubuntu patch
Status in metacity package in Ubuntu:
Invalid
Bug description:
There are several metacity bugs related to glitches / artefacts. I'm
not sure if this is a duplicate or not, but I have some more
information.
Using the ubuntu's patch to metacity "16-capture-before-unmap.patch" causes
the glitches to appear.
I reported it in the patch's original bug that tracks its development:
https://bugs.launchpad.net/unity-2d/+bug/696864
To reproduce one of the problems related to border redraw (copied from
the bug report above):
Using the Human theme, go to a clean desktop and open several
terminals. they will tile. Now hold alt-tab to quickly change the
focus between them. The focus rectangle will move between the windows,
and when it will disappear, the edges of the window decoration will be
removed, and not redrawn.
I have a feeling this is a cause for many glitches in metacity related
to window redraw. Since I can't consistently reproduce all of those
glitches, I have no way to be sure, but removing 16-capture-before-
unmap.patch from metacity *does* make the ones I noticed go away.
