In that thread: YouTube videos are playing in black and white
piratesmack, gezley and andrew.46 reported the problem concerning YouTube videos as well as described the solution. Unfortunately that solution doesn’t work for me.
I use Slackware 13.1 on ThinkPad X60s. Recently I updated Mozilla Firefox to 3.6.14 as well as Flash Player to 10.2_d151 version. I updated Firefox using slackpkg and Flash using packages provided by SlackBuilds.org.
Since that upgrade Firefox displays YouTube videos in red and yellow with oversized magenta shadows. I tried the solution suggested by gezley: I found some videos on the other sites and I tried to switch off “Enable hardware acceleration” option in Flash Player’s “Settings...” context menu. Unfortunately in my case I can see small window including that option but the window doesn’t respond to mouse clicks. “Enable hardware acceleration” option, a few tabs and “Close” button are all dead.
The same problem with YouTube videos appears in Opera so it isn't Firefox issue.
I switched off NoScript, Flashblock and Adblock Plus add-ons. Despite of that on most sites Flash Player’s “Settings...” context menu is unavailable. When it’s available Flash Player’s setting window is dead so I can’t switch off “Enable hardware acceleration” option.
Every help will be appreciated.
This is sample YouTube video screenshot displayed by Opera:

I just observed a new interesting effect. When I opened that picture
my graphic card covered all the screen with vertical brown lines: exactly 96 lines covering browser window and surrounding space including some dockable applications. Additionally it colored blue bold text on LinuxQuestions.org site into brown and reversed black text into white. Switching to another virtual console and coming back restored original colors.
To find the above picture on the main site
is enough to find “APS” string and to click in “Muestras: 12 MP” frame below the middle thumbnail in the top row.
