When I run a Windows application in Coherence mode, full screen, the window shifts every time the window gains focus. It's very annoying because I cmd-tab between applications quite a bit, and I happen to run my email application in Parallels (so lots of switching to/from it). I put together a video to demonstrate the issue. video of the issue Note: I found one similar issue on this forum but it was specific to the window leaving a space open for the dock.
To be honest, I've kind of given up on Coherence for now because of issues like this, but especially because of the unexpected logout issue on the latest MBPs (like my own). I just run full screen (Parallels full screen, not OS X full screen) all the time for now until this stuff gets fixed. You can still switch back and forth with cmd-tab with no issues. Steve
Unluckily I have been complaining on this exact same issue for almost a year now. The bad news is that, after upgrading to PD10, the same issue persists.
