Seeing an issue where Firefox is unusable on a Thinkpad T510 and Fedora Rawhide.

Easily reproduced by setting gfx.webrender.compositor.force-enabled to true.

Thanks for the report! Does it work when paired with gfx.webrender.software (it should)?

FWIW, it still works fine on my Radeon card.

Yes, it's most likely a nouveau bug or missing feature. If it's the later, then we may need to add a corresponding check, if it's a bug, then we should create a mesa issue. Or something in our code is build up on invalid assumptions - nouveau tends to be a bit special AFAIK. I should really get a nvidia device so I can test both nouveau and the prop. driver.

It does work when paired with gfx.webrender.software.

Severity: -- → S3

Note to myself: this is likely because we are using the GBM platform. If we ever pick up this work again, we'd need to switch to the divice/surfacesless platform in WaylandBufferDMABUF::Create, see bug 1770407
