Hi everyone


I have been experiencing weird display artifacts in Application Switcher/Dashboard after I disconnect from an external monitor. I started having this problem after I upgraded my MacBook Pro (mid-2010, Intel Core i5 with NVIDIA GeForce GT 330M 256 MB) from Snow Leopard to Lion. It might be an issue with Lion or it might just be an issue with my laptop.


The best way to describe this "weirdness" would be through a video:


The problem is reproducible. It happens after I disconnect from my external monitor. I notice this problem with both my monitors (Dell 20 inch and Dell 24 inch).


The problem used to be worse. The weird effect used to happen when I was using dual-monitor mode. When a window straddles both monitors, half of the window (the half on my MacBook Pro) exhibits the weird display issue. Fortunately, I managed to fix it by using deleting the Display Profiles for the external monitors (found in /Library/ColorSync/Profiles/Displays).


Needless to say this problem is very annoying. It also makes using the Dashboard impossible since the "dark" widgets makes it hard to read (especially in Dictionary). Any help would be appreciated.






MacBook Pro, Mac OS X (10.7.2)
