[Bug 1563287] Re: Right edge switcher stutters badly with only a few apps opened
Nice videos. Although I found I had to save them offline before they play nicely and the difference is clear. I've been wondering about spread performance actually. In particular how we implement texture smoothing. If it's just GL_LINEAR filtering that should be fast. But if someone has unwittingly turned on mipmapping then it could get very slow. ** Tags added: performance regression regression-proposed ** Summary changed: - Right edge switcher stutters badly with only a few apps opened + [regression] Right edge switcher stutters badly with only a few apps opened -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1563287 Title: [regression] Right edge switcher stutters badly with only a few apps opened To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1563287/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Kevin: I just tested and its all good on last OTA (image 30), so the delta is between then and now (rc-proposed).

[Bug 1563287] Re: Right edge switcher stutters badly with only a few apps opened
@Omer can you refine the regression claim a little? like when do you know the right edge performed better? - the reason i ask is so we can measure that and potentially determine what/when it regressed. also, in your assessment is there some minimum amount or particular set of applications needing to be opened in the spread to witness this? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1563287 Title: Right edge switcher stutters badly with only a few apps opened To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1563287/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Need to profile and check the code to see how this could have regressed. Stutter could be due to the GPU having to do too much work per frame, inefficiencies in unity8's code. Can't say for certain without measuring. I know of several optimizations to be done with spread still. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1563287 Title: Right edge switcher stutters badly with only a few apps opened To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1563287/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
