Title: [xmir] [multimonitor] Frames eventually get slightly out of order, look like glitches or typing will feel slow Status in Mir: Invalid Status in XMir: In Progress Status in “mir” package in Ubuntu: Invalid Status in “xorg-server” package in Ubuntu: Confirmed Bug description: Using ppa:mir-team/qa-testing and ppa:mir-team/qa-testing2, eventually the frames you see get slightly out of order and slightly lagged. I've only ever seen this bug in ppa:mir-team/qa-testing and ppa:mir- team/qa-testing2 so there's a reasonable chance it's come from one of the branches being tested there, which are not on trunk yet. The issue seems more pronounced with bypass (qa-testing) but eventually appears using qa-testing2 as well (no bypass). It doesn't seem to happen when using a single monitor. Only with multiple monitors. But possibly haven't tested enough to be sure. TEST CASE: Open a terminal in XMir and hold down a key. Expected: Key appears to repeat smoothly. Observed: Key sometimes appears to skip one character/frame ahead, and then back again. WORKAROUND (1) 1. sudo apt-get install compizconfig-settings-manager 2. ccsm & 3. CCSM > OpenGL > (untick everything except maybe "Sync To VBlank") WORKAROUND (2) Use simpler single buffering desktop environment, like Xfce. WORKAROUND (3) Unplug all external monitors. Use a single monitor :( To manage notifications about this bug go to: https://bugs.launchpad.net/mir/+bug/1216472/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
