Haven't delved too much into this issue Tux. On the Now
Playing thread, the video only has sound. When I go to YouTube, it's the same. Also, the VM takes a lot of resources though the 3 finger salute doesn't show this (i.e., my PC fan starts to get louder and PC runs sluggish). I tried all kinds of things too like add more virtual video RAM and also disabled Hardware acceleration (this actually made things worse; now no sound either and the fan really starts to chug; lol). Everything was bliss until I updated Virtualbox. Should have just left things alone. Won't be the first time weirdness happened when I updated VB. Oh well. I rarely view Flash videos anyway, so will just tolerate it and hope they fix the issue when someone else places a complaint (don't want to join the VB forum just to place a complaint).
