No more main-thread OpenGL in Firefox (important note for Linux users who use OpenGL)
Main-thread compositing with OpenGL is no more (bug 924403). The only option for OpenGL compositing is off-main-thread compositing (OMTC). This is the first big chunk of code removal following on from the layers refactoring, which began more than a year ago. It is very nice to finally be removing code and reducing the number of code paths in the graphics module.
Most users should not notice a difference. All supported configurations which use OpenGL (FirefoxOS, Android, modern OSX) already use OMTC. If you use OpenGL on Linux, however, read on.
OpenGL in Linux
OpenGL on Linux is not a supported configuration (i.e., fixing bugs is not a priority - we would love some volunteer help here, by the way, get in contact if you're keen). However, if you have good luck with your drivers, then it works pretty well and can be enabled by setting the 'layers.acceleration.force-enabled' pref to true. The main benefit is improved WebGL performance. OMTC on Linux also works pretty well, but is also not a supported configuration. If you want to continue using OpenGL on Linux for versions of Firefox 28 and later you will need to use OMTC. (Note that if you are considering trying OpenGL on Linux for the first time, you should use a new profile to make it easier to undo if your drivers are not cooperative. And be prepared for your system to crash, potentially).
Yep. I agree with you. I only tested the solution to make sure that it was working, but I won't use it because on my config the gains are marginal at most. The important point was to find the cause and the possible solution. Using OMTC is not perfect but as he said, the OP now is aware of what was the point and can make his own decisionPatH57 wrote:They also insist on the weakness of the driver support and be prepared for a crash potentially
Again your card is a native opengl card with heavy tweaks on the firmware so it is way more robust and can flush a lot of errors that his card may not handle
