This is not a driver problem, the driver renders exactly as firefox instructs it to. >>> 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.

I cant find it.

The underlying issues are fixed now, but firefox continues to use the same workaround that was needed before. -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
