Newbie here. Trying desperately to overcome this problem of neon-like color and distortion when I play a video. Often the sidebars of basically non-video screens (like email) have the same sort of wild colors and they often flicker.
It seems the consensus advice is to disable the hardware acceleration of Adobe Flash Player in the Settings tab (seen by right clicking on the video), but I've tried that and the box won't uncheck.
I've also tried the F11 method (below). No luck. What I need help with is implementing Method #1 (below, italicized). I know how to use the terminal and the advice doesn't seem that complicated, but if you could break it down into a step-by-step process for me, I would really appreciate it. Thanks! P.S. the problem and solution as stated below are from the superuser forum.
The latest official version (and supposedly the last version for Linux) of Flash player has some interesting issues on Linux systems. The biggest issues which have summarily been confirmed on the Ubuntu forums are:
YouTube videos have a red / blue color overlay Flash content shows through on other windows How do I fix this?
The commonly accepted solution to this issue appears to be disabling hardware acceleration for Flash player. This is usually accomplished by right-clicking the Flash content, selecting Settings and then uncheck the Enable Hardware Acceleration option, but in the affected version of Flash player, it isn't possible to uncheck that particular option (clicking it does absolutely nothing). As such, the following two work-arounds exist for disabling hardware acceleration:
Method 1: Create (or edit, if it already exists) the file /etc/adobe/mms.cfg and add the following configuration parameter to it: EnableLinuxHWVideoDecode=0
Method 2: Open a YouTube video and enable fullscreen mode. Then right-click, select Settings and uncheck the Enable Hardware Acceleration option. For some reason this only seems to work when Flash player is in fullscreen mode.
