Mission Control Borked on 10.10
 

Greetings,

I just upgraded from Mountain Lion to Yosemite. I have a recently purchased black USB3.0 -> HDMI adapter. I'm running DisplayLink Software version 2.3 Beta. I'm running just one other monitor (2 total). Spaces support didn't work much at all until I disabled "Displays have separate Spaces", and now I'm doing much better. I can use multiple Spaces.

What still doesn't work is Mission Control. When I go into either the mode that shows all application windows grouped together(CTRL-UpArrow) or the mode that shows all windows for current application (CTRL-DownArrow), I enter that mode only momentarily and then I am returned to my normal desktop display. Sometimes I see the Mission Controls screen for 3-4 seconds, other times I just get a flicker of windows. Even when the screen shows for 3-4 seconds, I can't manipulate anything.

I searched and haven't seen anything like this reported as a problem. I'm wondering if others have seen this and if anyone knows of a work-around.

TIA for any information or advice.

If you disable mission control animations, it helps a bit

Hi,

I have exactly the same and would welcome any advice or assistance in resolving this issue.

disable the mission control animations (google it) I posted a link to a guide but it appears the admins blocked that post
