Here's a screenshot of what I am talking about
I am just wondering what it is? I can kill it ~ 20% of the time, other times I can't. I try xkill usually, or right click on the border and choose kill.
Here's the explainaition of the pick:
The one box that looks clear is an "opened up" one. The black line above the clear box is the thing that shows up after playback. I grab the edge of it and can drag it open into the "unnamed" box.
It's random, I cannot automatically reproduce it, and it's not with any specific video type.
I am guessing it's a bug, but I am just wondering if anyone else has this problem, and maybe how they have fixed it???
