If you’re one of the many people who experience issues when watching Flash videos in fullscreen then the following tip by dodo3773 may help you out.
“What I did was right click on any flash video, go down to settings, and uncheck the box that says enable hardware acceleration. “ dodo3773 shares, continuing with the steps that fixed the problem
“Then open a terminal and type
- sudo mkdir /etc/adobe
- sudo su
- sudo echo \"OverrideGPUValidation = 1\" >> /etc/adobe/mms.cfg
“I added the sudo su as the second command because I was getting a permission denied error. After that I re-enabled hardware acceleration, closed Firefox, then opened it back up.
dod3773 ends on a positive stating “I have not experienced that problem again.”
