High CPU usage for simple tab switching #996

Open captain-majid opened 1 week ago

captain-majid commented 1 week ago

Describe the bug High CPU usage for simple tab switching, and heavy/slow switching, that didn't happen on Google Chrome v109 (the latest for Win 8.1)

To Reproduce Steps to reproduce the behavior:

  1. Go to a Google search page and duplicate the tab.
  2. Switch between the two tabs, and see CPU usage increase, and the switch takes ~1s, which should happen instantly.

Expected behavior No high CPU usage for simple tab switching, and light/quick switching.

Screenshots I'm just using Process Explorer to monitor that, can't give SS now.

Desktop (please complete the following information):

Additional context N/A

In my configuration, performance is about the same if not slightly better than 109. I believe it is linked to issues #889, #892 and #893. I'll try later with some lower-end Haswell systems that are also running 8.1.

hmm, can't confirm on Win 7 SP1 x64, both via UI and with Keyboard. Does it behaves same if you try to switch with KB? If yes - probably, issue not related with animations

Keyboard shortcuts for switching: Ctrl+Tab and Ctrl+Shift+Tab Ctrl+PageUp and Ctrl+PageDown

It happens with mouse or KB.
