Mission Control issue : some windows disppear
Hi all,
I'm experiencing some weird issue with Mission Control (it was with Lion ... and Mountain Lion did not correct this) :
You can see a video I've taken yesterday (sorry for the poor quality) : http://youtu.be/gAwIcF4JINc
As you can see :
- Mission-Control makes some of my windows (all windows in the example video) disappearing : they're reduced to "0" pixel
- Sometimes, the App icon stays visible (but I cannot select the windows as it is 0pixel size ...). Sometimes, even the App icon is not shown (often with Safari)
- Sometimes : only Safari is experiencing the issue ==> all other windows stay OK (Finder, etc... can be selected in Mission Control and Safari is the only 0 pixel sized). In the enclosed video, all apps are affected which is quite rare.
if I close the impacted app(s) and relaunch it, mission control handle the re-opened app(s) correctly.
Is there any way to fix this ?
I was hoping it was a 10.7.x issue but as 10.8 (incl. 10.8.1) is not fixing this, I'm losing patience.
Thanks in advance,
