WebGL linux

Good day everyone I have encountered technical problem running WebGL on Linux for some reasons.
Before, i had some issues with most demo´s(flickering graphics) then i installed the latest driver(11.2)and it worked perfectly fine. But this morning I tried to open webgl and it doesnt work anymore!

Anyone knows what could be the issue?

try starting the browser from a console window, in linux it should output any errors to the console window
