I am user of v2.05 version from steam.
I have been noticing this bug that has been happening a lot to me.
The preview window of any software opened remains open (at the bottom part of screenshot attached) and gets stuck until unless i bring back the cursor to any other software thus resulting preview changes and hence it starts to work correctly and preview gets dissapear.
I am attaching the screenshot link of the Bug where preview window gets stuck on my Chrome window forever.
Please solve this. now it is bothering me.
