Upgrading to Chrome today seems to have resolved this for me
I’ve had this issue recur ever since I started using Parallels last year. It was happening again the last couple days (mostly switching tabs wouldn’t show correct content, then I’d have to re-launch Chrome to fix). Issue seemed OK recently, then it came back (had the blackout issue in past, too).
My configuration:
• MacBook Pro (15-inch)
• Parallels Desktop 8 Build 8.0.18354 (latest as of 3/13/2013)
• Chrome Version 25.0.1364.172 m (latest as of update this morning, 3/13/2013)
• Flash Player: You have version 11,6,602,180 installed (latest as of 3/13/2013)
I suspect the issue is related to Flash Player, as has been the case in the past (noticed this week that Flash content was distorted and characters in Flash input fields were not displaying correctly). Chrome uses a built-in Flash Player. As a test and possible resolution, I had previously used the non-integrated Flash Player with Chrome, but have now switched back after updating Chrome today.
I updated Chrome this morning and the issue seems OK for now. So far, so good since updating.
