[Bug 1165353] [NEW] violent flashes when the main dock appears/diappears

 

Public bug reported:

My main dock visibility is set to hide when it overlaps any windows. Whenever the dock appears or disappears it flashes (or blinks) violently, or to describe it another way, it disappears for a fraction of a second several times during the animation.
This flashes are so violent they hurt my eyes and these disappearances seem to occur more when the mouse is inside the main dock's area.
My favorite animation would be the "zoom out", unfortunately it is one of the most violent ones, the less violent is the "move down" (but this may be just my perception, because the "move down" is a strange animation).

My system is:
Ubuntu 12.04 LTS
fglrx 8.960 (can't install a newer version, because fglrx>=9 does not support my Radeon HD 4570)
KDE 4.8.5
cairo-dock 3.2.0 (from ppa: http://ppa.launchpad.net/cairo-dock-team/ppa/ubuntu precise main)
compiz 0.9.7.8 (replacing kwin, but the flashes also appear with kwin with or without compositioning (or desktop effects as they call it))

Also, I have a dualhead xorg setup, but that one is also not to blame,
because if I start my laptop without an external monitor the flashes
still appear.
