User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:91.0) Gecko/20100101 Firefox/91.0
Steps to reproduce:
Using Firefox 93.
With Firefox 93 Mozilla is throwing away OpenGL compositing (rendering), only Webrender stays.
Actual results:
User will need compatible GPU for Webrender, otherwise FF will use software Webrender.
Even with fully compatible GPU on systems with slow CPU Webrender works slower than OpenGL compositing (~ 20% slower).
Here for slow CPU I mean this: using FF loads CPU to 100% continuously.
I cannot find exact data about Webrender system requirements. It worked on AMD Terascale 2 with OpenGL 3.3 support. Maybe it'll work with all AMD/ATI Terascale chips (Radeon HD 2000 series and newer), but not previous ones.
Expected results:
Working OpenGL compositing option, as usual.
Please provide info about Webrender system requirements.
