C8 crashes by clicking MIDI event or track

C8 crashes by clicking on midi event or midi track. All is happend only when i have in workspace two windows. When i switch to normal project view (full screen) and back this problem is gone but time to time is happend even after switch if im in “split” mode for long time. There are other problems with random size of channels in mix, but i want to point this. Anyone has same experience? To get better idea here is link to video.

I have a sort of similair problem. My Cubase 8 is crashing when i select the channel of my Virus TI. it doesn’t happen on any other channel, but just on the Virus TI Channel. It also doesn’t happen when i click on the midi’s. Not sure if this is because of this workspaces thing, because i don’t use that at all.
