I'm not sure if the problem I have is related but I have had problems with image sacling for a LOONG time now in several firefox versions. I use the binary nvidia driver. What makes me a bit confused is that if I nuke .mozilla directory and restarts I have no problem for some time but it always comes back after a week or two and once it starts it never gets good again. I have attached a small test case that shows what the problem looks like on my computer. ** Attachment added: scale_error.tar.gz http://launchpadlibrarian.net/32930153/scale_error.tar.gz -- Pixellated Images in Firefox/Opera due to incorrect EXTEND_PAD implementation in several video drivers https://bugs.launchpad.net/bugs/217908 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

** Description changed: [Problem] - Scaled images in Firefox, Opera, etc. look blurred or pixelated when zoomed. + Upscaled images in Firefox (and Opera) look pixelated when zoomed, edges appear jagged. [Discussion] This is because firefox is using nearest-neighbor interpolation for upscaling. It would look better if bilinear filtering were used by Cairo, which requires EXTEND_PAD. However, EXTEND_PAD is not implemented very well in several video drivers, and Cairo is unable to distinguish drivers that have good implementations from ones with bad ones, so it is currently using a client-side fall back which is deemed too slow by the firefox developers. Solving this requires updating each video driver to either implement EXTEND_PAD correctly or at least stop advertising it can do it when it really can't.

I'm sorry I haven't take the time to fully review the cairo patch, but I just want you to be aware of the work Eric Anholt did a couple of years ago to support the extend repeat modes and server-side gradients (but we failed to merge in a timely manner): http://cgit.freedesktop.org/~anholt/cairo/log/?h=server-gradients If you care to implement something along those lines, then I will be happy to merge it into upstream post-1.10 (which should give us a while to check the behaviour on non-Ubuntu systems). And also provide the circumstances where implementing h/w accelerated gradients becomes worthwhile. I suspect that even with s/w fallbacks switching to XRender gradients should be a performance win due to reduced transport costs and potentially improved pixmap allocation. -- Pixellated Images in Firefox/Opera due to incorrect EXTEND_PAD implementation in several video drivers https://bugs.launchpad.net/bugs/217908 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

The patch we're dealing with here is basically a (small) subset of David Reveman's patch. I'll see if I can find the time to update the gradient part of the patch next weekend and port it to xcb.

I suspect that even with s/w fallbacks switching to XRender gradients should be a performance win due to reduced transport costs and potentially improved pixmap allocation. I would think so, too. The nice thing here is that we are guaranteed that gradients are handled in the server by software, so we don't have to worry about drivers implementing them incorrectly. And if we ever decide to enable hardware acceleration for gradients, as Michel Dänzer suggested in [1], driver maintainers will be instantly aware of the issue, because most (all?) drivers will currently crash if the source's pDrawable is NULL.

Testing suggests (comments #45, #50, #71) that the closed source drivers fall back to software anyway, so this shouldn't be an issue. The artifacts that this may cause are very minor in any case.

Yes. Firefox has been using nearest-neighbor filtering to avoid hitting the slow path in cairo.

Phew, here they are. The one for -openchrome was already posted earlier, the one for -ati is obsolete now.

I just wanted to point out that the same (page-zoom) issue that exists in Opera is still the same even though it has been fixed in Firefox. I was initially under the impression that the page-zoom-image-distortion issue in both browsers was related, simply bcos the poorly zoomed images in both browsers displayed similar symptoms/artifacts.

Okay, none of the other drivers (except nouveau, which is doing the correct thing, it looks like) accelerate Compose/repeat at all, so the list of affected drivers should be complete.
