Created attachment 171176 [details] Screenshot SUMMARY My shortcuts: Meta+Tab for Walk through windows, Meta+` for Walk through windows of current application. I selected "Only one window per application" in System Settings -> Window Management -> Task Switcher See below. STEPS TO REPRODUCE 1. Have multiple windows of same applications (e.g. 3 Alacritty windows) 2. Meta+Tab (don't release Meta key), window switcher shows up, and there's 1 Alacritty window (expected) 3. Then hit ` key (keep holding Meta key) to "walk through windows of Alacritty" OBSERVED RESULT There should be 3 Alacritty window thumbnails in window switcher EXPECTED RESULT There's only 2 thumbnails, the third thumbnail slot is present but the thumbnail is missing SOFTWARE/OS VERSIONS Linux/KDE Plasma: Arch Linux (available in About System) KDE Plasma Version: 6.1.1 KDE Frameworks Version: 6.3.0 Qt Version: 6.7.2 ADDITIONAL INFORMATION Honestly after Plasma 6 update there's several new bugs and performance decreases. Sorry but I have to complain, the experience has been bad.
Cannot reproduce on Wayland with current git master with any app I try it with, including Alacritty. Does it reproduce for you with all apps tested, or only Alacritty?
Yeah, with konsole, alacritty and Dolphin, at least. Haven't tested with other apps yet.
Adding new info here, this issue happens to all other task switchers, like Compact, Sidebar, Large Icons e.t.c.. And I'm using Xorg, and I cannot test it on Wayland due to old graphic card. @Nate Graham knows about it and uses Wayland, so I guess it's probably an Xorg only bug?
