I bisected this and it turned out to be much older than I expected. Looks like it happened between 2015-09 and 2015-11, though beyond that I'm not sure. We don't have any rc-proposed images old enough for a more fine-grained inspection.
Problem exists in: * krillin rc-proposed 329 (pay-service 15.10+15.04.20160413-0ubuntu1) * krillin rc-proposed 315 (pay-service 15.10+15.04.20160324.1-0ubuntu1). * arale rc-proposed 306 (pay-service 15.10+15.04.20160324.1-0ubuntu1). * arale rc-proposed 262 (pay-service 15.10+15.04.20160114-0ubuntu1) (oldest rc-prop image on our servers). * krillin rc 39 (OTA 8.5) (pay-service 2.0.0+15.04.20151103-0ubuntu1) * krillin stable 27 (OTA 8) (pay-service 2.0.0+15.04.20151103-0ubuntu1) I don't see the issue in: * krillin stable 26 (OTA 7) (pay-service 2.0.0+15.04.20150914-0ubuntu1) * krillin stable 24 (OTA 5) (pay-service 2.0.0+15.04.20150706-0ubuntu1) BTW, this is really easy to check for. Flash an image, go to the app store, tap a paid app (I've been using "Cut the Rope" since it's on the front page today), tap the $2.99 button. Watch 'top' in a shell at the same time, to see if pay-service jumps up to 99% CPU. No need to even try to log in; it's sufficient to merely bring up the login UI. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1580195 Title: High CPU load on Payment screen To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1580195/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
