[Touch-packages] [Bug 1563287] Re: [regression] [OTA-10] Right edge switcher stutters badly with only a few apps opened
CPU usage during spread animation: OTA-9: 60% OTA-10: 70% So that's a noticeable increase but not an indication we're CPU bound at all. We are close to being CPU bound, but OTA-10 isn't that much worse than OTA-9's CPU usage. The relatively low increase in CPU usage, high increase in render time, and sensitivity to viewport clipping (comment #21) all point to the regression being in the GPU load (Qt/QML/shaders). ** Changed in: qtmir Status: New => Confirmed ** Summary changed: - [regression] [OTA-10] Right edge switcher stutters badly with only a few apps opened + [regression] [OTA-10] Spread animation stutters badly with only a few apps opened -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unity8 in Ubuntu. https://bugs.launchpad.net/bugs/1563287 Title: [regression] [OTA-10] Spread animation stutters badly with only a few apps opened Status in Canonical System Image: Confirmed Status in Mir: New Status in QtMir: Confirmed Status in qtmir package in Ubuntu: Confirmed Status in unity8 package in Ubuntu: Confirmed Bug description: Regression in OTA-10: tested on krillin and arale on rc-proposed. also I tried the fix for bug 1556763 but that's not related to this as well.

Also confirmed that OTA-10 images 31 and 32 are slow only in the spread, and only with a few windows or more. The Mir performance report for Unity8 is showing smooth performance in Unity8 other than a well populated spread. In fact, performance of the spread varies dynamically according to the number of windows in it. If you view the top of the window stack then you get 4-5 windows visible and it's slow and stuttery. If you go to the bottom of the stack though and wiggle your finger, it becomes fast again -- because at the bottom of the stack only two windows come into view simultaneously. So the regression is probably somewhere between Unity8 and QtMir, where our ability to put multiple surfaces on screen at once has degraded. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unity8 in Ubuntu. https://bugs.launchpad.net/bugs/1563287 Title: [regression] [OTA-10] Right edge switcher stutters badly with only a few apps opened Status in Canonical System Image: Confirmed Status in Mir: New Status in QtMir: New Status in qtmir package in Ubuntu: Confirmed Status in unity8 package in Ubuntu: Confirmed Bug description: Regression in OTA-10: tested on krillin and arale on rc-proposed. also I tried the fix for bug 1556763 but that's not related to this as well.

Here are performance measurements of OTA-9 and OTA-10's Unity8 spread animation on krillin.
