[Bug 1883369]
Really we'd want to avoid this transition from subpixel AA to grayscale on our side in the first place. But looking back, if you were using hintnone, this might have been fixed recently by bug 1732577. Worth a try in nightly to see if this is still a problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1883369 Title: Weird font rendering on certain website with firefox To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/1883369/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Comment on attachment 9226932 Bug 1714511 - use vqmovun_s16 for packing pixels. r?sotaro ### Beta/Release Uplift Approval Request * **User impact if declined**: Enabling Software-WebRender on ARM platforms can lead to visual artifacts. Should not impact x86 platforms or non-SW-WR configurations. * **Is this code covered by automated tests?**: No * **Has the fix been verified in Nightly?**: Yes * **Needs manual test from QE?**: No * **If yes, steps to reproduce**: * **List of other uplifts needed**: None * **Risk to taking this patch**: Low * **Why is the change risky/not risky? (and alternatives if risky)**: Software-WebRender on ARM is not deployed by default to release. Must be pref'd on. However, many users on tier-2 platforms like ARM/Linux are pref'ing the feature on, and it would be nice if we just supplied the fix to them so they don't need to manually apply it to their build. * **String changes made/needed**: -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1930982 Title: Firefox 89: webrender breaks videos on Raspberry Pi To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/1930982/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Sotaro, can you see if my vqmovun_s16 patch fixes this or not? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1930982 Title: Firefox 89: webrender breaks videos on Raspberry Pi To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/1930982/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

The circumstantial evidence "seems like" something in the function here (https://searchfox.org/mozilla- central/source/gfx/wr/swgl/src/composite.h#534) is underflowing. But I would need someone who can reliably reproduce the issue to find out where in those math equations are actually doing so. I tried testing in my patch if the additions were the culprit, but that seems unlikely. It's possible the multiplications "rbCoeffs * uv" or "gCoeffs * uv" are underflowing based on whatever values the ARM video codecs seem to be supplying. However, this is not happening on x86 at all, which is strange, and it is also happening on ARM across platform, which is further strange, since there isn't really much in the way of platform specific code here. Sotaro, might you be able to investigate this? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1930982 Title: Firefox 89: webrender breaks videos on Raspberry Pi To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/1930982/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Do you use hintfull in your fontconfig hintstyle settings? It might be that when it is rendering with subpixel AA it uses the LCD-hinting algorithm, whereas when it goes to grayscale it has to use the normal hinting algorithm. If so, if you try using some other hintstyle like hintslight explicitly in your fontconfig settings, does it fix it? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1883369 Title: Weird font rendering on certain website with firefox To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/1883369/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Jonathan, seems vaguely like a layout issue? I think we have seen issues in the path where depending on how the CSS of the site was doing things for onhover (potentially animation/will-change related), it could route through different AA/hinting settings somehow? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1883369 Title: Weird font rendering on certain website with firefox To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/1883369/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
