Hi Sebastian, Now that was an interesting observation. I did some test to find out more about the issue.
I used another installation here for comparison: lucid-64 bit fully updated with an ATI graphics card, HD2600 Pro and lucid's own xserver-xorg-video-ati_1.6.13.0-1ubuntu5 driver. I compared libcairo2_1.8.10-2ubuntu1 (and libpixman-1-0_0.16.4-1ubuntu2) to the maverics libcairo2_1.9.12-1 (and libpixman-1-0_0.18.2.1). It was indeed interesting to note that with ATI graphics card there was no color blend issues with maverics libcairo2 and libpixman-1-0, but the sluggishness of the desktop was clear and easy to observ. So at least new libcairo2 still makes system slower to respond. On the other hand, I also tested my maverick installation with NVidia graphics card, GTX285 + nvidia-current_256.35-0ububtu2 driver. When I downgraded the libcairo2 to the version 1.8.10 (lucid), the colors blend issues and sluggishness both were gone. -- [maverick] libcairo2 fails to render color blends correctly with certain themes https://bugs.launchpad.net/bugs/601220 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
