Hello,
I am building an old Pentium 4 661 build and wanted to use it as an everyday machine with SSD and 4GB DDR2, using linux as o.s. being lighter and going for Wine app to launch old games and I found a Radeon X300SE 128M (Dell) video card that felt like a good basic linux friendly passive card with an old style OpenGL 2.1 acceleration I was sure it would have worked in everything, web browser included. I found instead that modern Chromium based browsers won't use its OpenGL/hw acceleration while Firefox still can (tested with online WebGL test) and wondering why the R300 & similiar gpu series seems to be discontinued; even disabling the blacklist from the flags page it still don't use its OpenGL 2.x acceleration that should be enough for most web apps. It works in firefox, it works in the 3D apps with the quite good Radeon driver but something changed with this web browser it use the software renderer even when everything is enabled.
Any suggestions? I tried also a HD4650 card that instead works ok as expected but I wanted to use a very low end old OpenGL compatible card. I suppose these old GPU begin to be blacklisted in Chromium even if they should have the acceleration needed for basic rendering (beside video decoding of course). The card is seen as OpenGL 2.1 accelerator and even in the :gpu page of the browser it both shows the software rendering layer and the device information at the end of the page with the Hardware acceleration theorically available but not really used. I suppose this line explain the problem:
Gpu compositing has been disabled, either via blocklist, about:flags or the command line. The browser will fall back to software compositing and hardware acceleration will be unavailable.
Disabled Features: gpu_compositing
Thanks
