           Summary: Branch 1.9 of libcairo2 breaks display with nvidia
                    proprietary drivers
           Product: cairo
           Version: 1.9.14
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: general
        AssignedTo: cworth at cworth.org
        ReportedBy: benshalom at gmail.com
         QAContact: cairo-bugs at cairographics.org


I use geforce 9500m with nvidia 256.44 drivers on 64-bit ubuntu 10.10.

The system is very sluggish and unresponsive comparing to prior experience with
ubuntu 10.04, which used libcairo2 1.8. Compiz animations stutter and window
contents are being drawn slowly. Moreover, there are elements the system fails
to paint correctly with the nvdia driver:

1. Selected menu items and progress bars are brighter then they should be.

2. The lovely glowing dots below docky icons, which mark which app is being
ran, become large, ugly grey blobs.

The issues disappear if I downgrade libcairo to the 1.8 branch.

Screenshots are found in the ubuntu bug report
(https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/612614). This bug has
links to many reports of people who suffer from similar issues.
