I can confirm this error, using a ATI X800XL with fglrx, output from lspci:

The same thing (extreme slowing down) happens from time to time, without doing a resize.. perhabs there is something else, which triggers this issue. Attached is a image, which shows the blue overlay. ** Attachment added: "Image with blue overlay" http://launchpadlibrarian.net/9416611/resize.png -- compiz slows to a crawl on resize of a window https://bugs.launchpad.net/bugs/140816 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
