Still a problem with Plasma 6 Wayland, although much less frequent. The previews also flicker each time the cursor leaves the preview area, and can promptly refresh and show themselves, but i'm not sure if it's connected to this bug.
*** Bug 477478 has been marked as a duplicate of this bug. *** I sometimes face the same issue when switching between windows using Alt+Tab - previews are empty. Since a recent update to 6.1.1 Wayland + Pipewire 1.1.83-1.1 on openSUSE TW, I no longer have window previews in the icon only task manager but also only black content for screens and windows in OBS Studio 29.x and 30.x (including the flatpak version).

Can confirm the issue on Tumbleweed. (In reply to equeim from comment #6) > Can confirm the issue on Tumbleweed. Looks it's already resolved again with the latest snapshot + pipewire 1.2.0. Sorry for the noise. :) I'm still facing this issue on openSUSE Tumbeweed 20240629 with pipewire 1.2.0. It take my comment 7 back, it's still reproducible: 1) Sometimes, when the popup becomes visible, it takes a short delay of ~100 ms until the preview is shown 2) or it shows first am empty popover but after ~ 1 second the app icons appear but no preview in case of multiple opened windows of an app, sometimes for the first window the preview is shown but for the others only the icon. Again always also with a delay I see no errors in the pipewire debug log, but at least a deprecation warning: `kwin_wayland[27271]: D pw.stream [stream.c:2437:pw_stream_queue_buffer]: deprecated: use pw_stream_trigger_process() to drive the stream.` Worked with 6.1.0. Now broken again with 6.1.1 It got fixed upstream. The fix has been backported to 1.2 branch too. (In reply to Vlad Zahorodnii from comment #12) > It got fixed upstream. The fix has been backported to 1.2 branch too. Thank you so much for looking into it! :) I have just updated to pipewire 1.2.1-1 on my system. Now the bug is harder to reproduce, but the tooltip of a task is still failing to appear sometimes.

I believe there was a bug report for that, but I cannot find it anymore. Could someone please link it here? Thanks! :)

Created attachment 161143 [details] journalctl -f SUMMARY As per title, previews often fail to show up for me, they're just blank. The worst issue is its very hard to reproduce: there seems to be an almost 50/50 chance whether they'll appear or not. If you have a group of windows sometimes no previews are there, sometimes only one is empty, sometimes it'll take 1-2 seconds to appear. But most often, if no previews appear, you have to let them disappear and click on the plus or hover again and this time they'll be there. I have seen multiple bug reports about this and many seem to be marked as fixed and yet i've never found the previews to be reliably working. I was always told having minimized windows not showing thumbnails was a limitation of X11 and something Wayland would fix but it's just not reliable. I'm not sure if the logs contain anything useful but i've attached journalctl output. I rely on these a lot so having them working would be grand. Thank you for reading. STEPS TO REPRODUCE 1. Create a few windows of the same type 2. Hover or click on the plus icon on the icon only task manager OBSERVED RESULT empty window previews EXPECTED RESULT windows previews are working Operating System: Arch Linux KDE Plasma Version: 5.27.7 KDE Frameworks Version: 5.109.0 Qt Version: 5.15.10 Kernel Version: 6.4.11-arch2-1 (64-bit) Graphics Platform: Wayland
