[Desktop-packages] [Bug 1606122] Re: Cairo drawing coordinates are broken w/nouveau (affects xfwm4)
Thank you for taking the time to report this bug and helping to make Ubuntu better. We are sorry that we do not always have the capacity to review all reported bugs in a timely manner. Ubuntu 16.04 (xenial) reached end-of-standard-support on April 29, 2021. I'm setting the status of this bug to 'Incomplete' as it's not seen any activity for some time. If this is still an issue when using a currently maintained release of Ubuntu then please let us know which one(s) otherwise this bug report can be left to expire in approximately 60 days time. ** Changed in: xorg (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1606122 Title: Cairo drawing coordinates are broken w/nouveau (affects xfwm4) Status in xorg package in Ubuntu: Incomplete Bug description: I'm using xfwm4 with Xubuntu 16.04. With compositing enabled, and when I cycle through windows with Alt-Tab, xfwm4 draws an opaque rectangle bordering a candidate window, and it fills that rectangle with a semi-transparent blue color. When I use the nouveau driver, the filled rectangle is clipped. The problem does not reproduce with the proprietary nvidia driver. It seems as though a drawing command should be issued using a window- relative coordinate, but sometimes is instead issued using a screen- relative coordinate. I extracted relevant bits of xfwm4 into a small test program that reproduces the problem. The test program creates a transparent XWindow at (100,100) with size (210,210). It draws six rectangles centered inside the window of varying parameters. Two of them are drawn at the wrong place. xfwm4 should be off-the-hook, I think, unless it's doing something wrong (e.g. unspecified/undefined behavior). $ lsb_release -rd Description: Ubuntu 16.04.1 LTS Release: 16.04 $ apt-cache policy xserver-xorg-video-nouveau xserver-xorg-video-nouveau: Installed: 1:1.0.12-1build2 Candidate: 1:1.0.12-1build2 Version table: *** 1:1.0.12-1build2 500 500 http://us.archive.ubuntu.com/ubuntu xenial/main amd64 Packages 100 /var/lib/dpkg/status $ apt-cache policy xfwm4 xfwm4: Installed: 4.12.3-1ubuntu2 Candidate: 4.12.3-1ubuntu2 Version table: *** 4.12.3-1ubuntu2 500 500 http://us.archive.ubuntu.com/ubuntu xenial/universe amd64 Packages 100 /var/lib/dpkg/status I created a video demonstrating the problem in xfwm4: https://www.youtube.com/watch?v=8dZN80tMA6M.

The bug doesn't reproduce anymore. Both the extracted-from-xfwm4.c test program and xfwm4 now work, on my Ubuntu 16.04 machine with the NVIDIA GeForce 750 Ti card.
