Bug ID: 366603 Summary: First alt-tab press not handled Product: kwin Version: 5.7.3 Platform: Archlinux Packages OS: Linux Status: UNCONFIRMED Severity: normal Priority: NOR Component: effects-tabbox Assignee: kwin-bugs-n...@kde.org Reporter: mark...@gmail.com I've notices this for a while now, i think it's since the shared QQmlEngine. But i was never quite sure if i just mis-pressed alt-tab or if the first one really didn't get handled. Now i sat down and really test this. It's really not being handled. Reproducible: Always Steps to Reproduce: 1. Restart your Plasma 5 environment. Just killing and restarting plasmashell does not make this issue visible. Better start with a freshly started environment form the login manager. 2. Open 2 applications 3. Press alt+tab 4. Nothing happens 5. Press alt+tab again 6. now it works :) Actual Results: Pressing alt+tab for the first time after logging in from the loginmanager (and starting 2 apps afterwards) does nothing. Pressing alt+tab for the second time works as expected. Any alt+tab presses afterwards works just fine. Expected Results: The first alt+tab press should also show the window switcher I tested this on: - Intel desktop with nvidia graphics - intel laptop with intel graphics - virtualbox environment All show the very same issue. -- You are receiving this mail because: You are watching all bug changes.
