I'm using a MBP with a second (external) monitor and since I upgraded from Snow Leopard to Lion, I encountered some display issues that appear in the Application Switcher, and sometimes in the menu-bar.
In case of the menu, the font in the dropdown appears with jagged edges, as if there suddenly was a huge contrast-change affecting only the menu-items.
In case of the Application Switcher, the effect is even worse as shown in this image:
Interestingly, this glitch seems to only affect overlays like the Application Switch or the menu. The rest of my OS and all Applications are looking fine.
If I go to System Preferences and choose another color-profile for my monitor, the issue is gone. If I select the previously selected color-profile, the issue appears again. The issue happens with every profile though. So if I choose Adobe RGB (1998) and restart my computer, the issue occurs. It disappears when I select another profile, for example Apple RGB. After a restart, the glitch will re-appear (even with the newly selected Apple RGB) and only a profile-change will remove it.
It's not too big of a deal, but if anybody has some pointers how to resolve this, I'd really appreciate it. Btw. the issue appears on different monitors, so it's not some monitor-hardware fault or anything.
Update: I was under the impression that the issue reappears after a restart. That assumption was wrong, the issue appears whenever I switch the external monitor (eg. change from monitor at work to the one at home).
