Another finding is that whoever rendering eats up all the CPU of one core When Xorg is rendering, %CPU of Xorg is close to 100% When tmux is rendering, %CPU of tmux is close to 100% Is there a way to dump out the stack to see what's wrong? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to fglrx-installer in Ubuntu. https://bugs.launchpad.net/bugs/1550910 Title: fglrx renders extremely slow in latest kernels Status in fglrx-installer package in Ubuntu: New Bug description: I am using latest development version of xenial (ubuntu 16.04).

I mean the "official" driver downloaded from support.amd.com failed to build. Slow rendering appears after "apt install fglrx" and reboot. Installing prebuilt fglrx binaries seems to success. So I think the bug is related to fglrx. ** Package changed: mesa (Ubuntu) => fglrx-installer (Ubuntu) ** Also affects: mesa (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1550910 Title: fglrx renders extremely slow in latest kernels Status in fglrx-installer package in Ubuntu: New Status in mesa package in Ubuntu: New Bug description: I am using latest development version of xenial (ubuntu 16.04).

Reassigning to Mesa. From your bug description you have pointed out that fglrx failed to build so you're not using it. The real issue then is that the Mesa radeon driver is not performing. ** Package changed: fglrx (Ubuntu) => mesa (Ubuntu) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1550910 Title: fglrx renders extremely slow in latest kernels Status in mesa package in Ubuntu: New Bug description: I am using latest development version of xenial (ubuntu 16.04).
