** Description changed: - 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. + Using multiple monitors, eventually the frames you see get slightly out + of order and slightly lagged. Particularly when only one monitor is + updating. TEST CASE: - Open a terminal in XMir and hold down a key. + Open a terminal in XMir, move it onto a single monitor, 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 :(
