DefaultDepth 30

TRUE

MESA_VENDOR_ID
0x10de
MESA_DEVICE_ID

ERROR
X error, error_code=10, request_code=152, minor_code=5
Then, I start firefox and it is very laggy.
Actual results:
Firefox is very laggy, checking about:config shows that many gfx entries are disabled with: FEATURE_FAILURE_GLXTEST_FAILED
Forcing:
gfx.webrender.all = true
fixes all issues, suggesting that only the glxtest is buggy. But it is buggy only with DefaultDepth=30 (10 bit color mode), with DefaultDepth=24 (default), it works fine.
Expected results:
glxtest should not return error in 10 bits mode, and firefox should have hardware acceleration enabled.

The Bugbug bot thinks this bug should belong to the 'Core::Graphics' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

We don't currently support 10 bit color depth in Firefox.
