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. The right edge switcher on both krillin and arale stutter when I drag it from the right edge and then swipe through the list of opened windows. This was not the case a few months ago, so we clearly regressed here.
