Hi,
I have a new MacBook and the screen seems to go a bit wild after longterm screensaver/sleep time or other longterm use of programs that utilize fullscreen mode. I haven't found a consistent app that causes the problem everytime and am a bit baffled.
The issue is resolved with a restart or logout.
A sample image should appear below. Please let me know if you have any suggestions as to how to prevent this issue (or previous threads that have already covered it).
Thanks,
John
