[Bug 351186] Re: [M76] [ubuntu 9.04] [ubuntu 9.10] [ubuntu 10.04] slow unminimizing with ati card and desktop effects enabled
In response to #420:
Last time I installed the backclear.patch on ATI Mobility HD3400
hardware I noticed distorted and weird pixels when opening new windows.
They disappeared as soon as contents was painted into the window.
However it suggests what the source code comments say:
+- /*
+- * Copy bits from the parent into the new pixmap so that it will
+- * have "reasonable" contents in case for background None areas.
+- */
Without this patch- there are NO distorted and arbitrary colored pixels
when opening new windows. I would all this a regression (besides the
performance improvement) within ATI hardware already.

What I just did is install the patch on -intel hardware (GM965 to be
more specific) and expected to see those weird colored pixels when
opening new windows. However windows look fine upon creation.
