This month I was looking at some videos I downloaded. VLC was being wierd. Found I had 2 version,3.x and 4.x. My window session froze yet again. I knew version 4 had issues awhile ago which is why I installed the previous version. I did a complete purge of both versions and just installed version 3.x and dependencies from the command line. The results look promising. VLC works properly now and my WM has not frozen since. I hope its fixed.
