I know that there were many questions about youtube giving blackscreen, but I went through a lot of them on none was my problem. I am using Chrome 32bit, basically, youtube sometimes stops working for me, giving a black screen in the place of the video, without any controls or anything. I tried using only Pepper flash, only adobe-flashplugin and both at the same time and it didn't work. The thing is, after some time it starts working again all by itself, without me changing pretty much anything. Which is completely bizarre, a bug that starts and stops happening all by itself, without any apparent connection to what am I doing on my computer. Also, everything else flash related works on other sites and I tried switching to HTML5 version on youtube.com/html5 with still no success.
