Comment 143 for bug 709461

I have 2 PCs which had 10.10 and 11.04 during last half-year. One of them never encounter this bug and second one encounter it permanently. No matter what WM is used - Gnome2, Unity, KDE - invisible windows appear pretty often. One and only way to quick fix it - Alt-F4 until all windows closed. Right after that almost any opened window creates invisible window again.
This bug persists very long time and makes my second computer totally unusable with *buntu. Dunno, is it hardware-related, but if it helps:
Affected PC: ATI Radeon HD2600, AMD Athlon64 X2 3800, Wireless Logitech mouse LX6, MB ASUS M3A78-CM.
Non-affected: ATI Radeon HD3870, AMD Phenom 9750, Wireless Logitech mouse LX5, MB Gigabyte GA-MA790FX-DS5
