Firefox hwaccel flag and ATI-drivers

[esperto]

Hi all,

A few weeks ago I've updated from firefox 42 to 42-r2 and everything went to shit, firefox window was slow to update itself, got blank screens and had to click outside the window every time I'd to scroll or clicked a link to force a redraw.
After several tests yesterday I removed the hwaccel flag and it is back to normal again, does anyone knows how can this be solved (have the hardware accelleration back)?

I'm on kernel 3.18.9 (gentoo-source) and ati-drivers version 15.9-r1, my graphics card is a HD7770.

thx
Rafael

I'm experiencing the same issue also with random crashes on some scripts with embedded flash/html5 youtube videos. My solution and to keep hw acceleration too was to toggle "webgl.disabled" flag on in about:config. Previously I couldn't access the about:support tab to check for hw acceleration which now is OK.
Good luck!

Just tried toggling webgl.disable and recompiled with hwaccel flag on, didn't work, same as before.
This is strange.
Where can I find 42-r2 changelog? maybe I can find out what have changed.

Hardware acceleration never worked in Firefox with ati-drivers. hwaccel flag just force-enables it, but the result is unusable browser. If you want hardware acceleration, switch to open source drivers or use Chome (it supports hardware acceleration with ati-drivers).
