Regarding fixing bug 1517205, it appears the new EGL synchronization was only ever required to resolve problems with software clients. But this bug is mostly about hardware clients (Unity8 rendering to USC).
So history would seem to suggest that we could live without the new EGL synchronization on hardware clients, and get the performance back. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to mir in Ubuntu. https://bugs.launchpad.net/bugs/1563287 Title: [regression] [OTA-10] [Mali GPU] Spread animation stutters badly with only a few apps opened Status in Canonical System Image: Confirmed Status in libhybris: New Status in Mir: Triaged Status in Mir 0.20 series: Triaged Status in Mir 0.21 series: Triaged Status in QtMir: Invalid Status in mir package in Ubuntu: Triaged Status in qtmir package in Ubuntu: Invalid Status in unity8 package in Ubuntu: Invalid 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.
