Many graphics drivers didn't use to accelerate composite operations with repeat type PAD (and REFLECT) correctly. This was a year ago; i believe these issues have long been fixed. > Could a small test program be written to show the error ?? has maybe > someone written one already. There is a very simple test case attached to this very bug report. Its source surface is only 2x2 (IIRC), which might not hit an accelerated path on every driver; there's a test case with a larger source surface attached to the -ati driver bug report. > This needs to get solved one way or the other having a fix outside the > normal distribution is not acceptable. but working around the problem in > only firefox obviously is not the correct fix. No, firefox is the correct place to fix this issue. Firefox asks for nearest-neighbor interpolation because on unpatched cairo 1.8.6, bilinear filtering forces a slow client-side fallback to insure correctness. -- FFe: 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
