Screen refresh problem 10.6.5 / Win 7 / Parallels 6 - WORKAROUND FOUND
Have been having a strange screen refresh problem lately - where certain windows sub-windows blank to white once a minute or so, and then will redraw when the mouse hovers over those areas.
See: http://www.youtube.com/watch?v=t8l_soyPkpY for an example screencast
It MAY be related to upgrading to 10.6.5.
Running Parallels 6 (Build 11828), Windows 7 Ultimate x64, 1gb memory for guest, 10Gb memory, 8-proc Mac Pro host
Anyone else seeing this?
Thanks
UPDATE: Parallels tech support identified that it was the task that synchronizes the VM's clock with the Mac -- so if you turn off sync (Configure > Options > Advanced > Synchronize time with Mac) then the problem goes away. Hopefully a fix will be available in a future release, but this workaround works fine for me.
