I opened catalyst control center to see what its was, i didn't change anything and now when i full screen a youtube and hulu the screen will be black and the loading bar at the bottom will be stuck. I also noticed that now when i play minecraft all the blocks have a black out line i cant get rid of. I tried deleting my .minecraft and that didn't fix it.
on the backside suitable hand corner of the small reveal, there's a field with a smaller field in it (suitable of the quantity), press that, it provides you with the finished reveal. you could press the comparable button once you opt for to bypass decrease back. The button would have a crimson X in it this time.
Catalyst control center? You, my friend, have a Radeon graphics card. What's happening is that somewhere you have Anti-Aliasing turned on. Go back into your catalyst control center and anywhere where there is an option to 'use application settings'- select it. It's supposed to improve your graphics quality, but there are a lot of bugs with it on a whole bunch of applications and games- including Minecraft. Oh, and as for the youtube thing- alt+tab should show you where your video has disappeared to. Yes, I know- it's bloody weird, but flash is buggy as heck, and Radeon graphics cards are weird; I should know- I have one too! That should do the trick! If it doesn't work then there's likely an extra option somewhere that you haven't ticked to 'use application settings'.
