[Bug 1001550] Re: LibreOffice Calc causes high CPU usage in Xorg when displaying "marching ants"
It's there (again?) in LibreOffice 5.2.0.4 (from ppa as well as document foundation build). I am still on 14.04 because the update to 16.04 utterly failed, but running xenial's kernel and NVIDIA proprietary driver nvidia-352. see here: - https://ubuntuforums.org/showthread.php?t=2333447 - https://bugzilla.redhat.com/show_bug.cgi?id=1308700 The Title should not even be marching ants - it's generally not usable, possibly in the config NVIDIA proprietary driver and gnome, cinnamon or unity.

I can confirm Yulianto´s comment that disk-I/O is rising very high as well. My system has almost the same properties that Nathan´s has.

Similar problem. When marching-ants show up, libre-office bottom bar flashing as well. CPU usage rising, disk-I/O (writing) rising as well, at steady. CPU at 50% per core, disk-I/O at 200kB/s. Then, when I go to any other window (ie: gedit, chrome), do some selection, and press Ctrl-C, then everything goes back normal. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1001550 Title: LibreOffice Calc causes high CPU usage in Xorg when displaying marching ants To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1001550/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1001550] Re: LibreOffice Calc causes high CPU usage in Xorg when displaying marching ants
I have kind of the same problem. When i start up libreoffice writer/calc etc. it hangs, it doesn't get that far that it shows any text, just gray. And thye cpu and memory usage goes from ca. 10percent to 99-100 percent for both, then everything goes really slow. Even if i try to open new document, it hangs... when i finally get to kill the process, resource usage goes down to normal again. This is on my home computer (new install 12.04), and my work computer(upgrade 12.04 from 11.10).

[Bug 1001550] Re: LibreOffice Calc causes high CPU usage in Xorg when displaying marching ants
Disabling Hardware Acceleration and Anti-Alaising see a notable decrease in CPU usage; it still spikes but doesn't bring my system to a crawl. Notably: This may be tied to the NVIDIA PowerMizer settings. So when you're in Adaptive mode, it's supposed to spool up the clock speed on the card when the power is needed. It looks to me like the marching ants selection is taxing on the GPU, but PowerMizer often fails to increase the card's clock speed when it's taxed by LibreOffice. What I'm finding is: + If do something else that taxes the GPU, like initiate a transparent window somewhere, PowerMizer increases the clock speed, and LibreOffice begins performing better + If I set PowerMizer to Maximum Performance rather than adaptive, the problem goes away. (however, Xorg still uses about 33% CPU whenever the marching ants are present) I have not had a chance to try the nouveau drivers yet. Do you think it's worth a continued investigation, or does this sound like an NVIDIA bug? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1001550 Title: LibreOffice Calc causes high CPU usage in Xorg when displaying marching ants To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/1001550/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
