SUMMARY I am using Plasma 6.1.3 on Fedora 40 (KDE spin). When I connect an second monitor or projector, select "Unify outputs" and activate the overview effect, the effect is only shown in the primary monitor; the second monitor only shows the background image. Previously (in Plasma 5.27) when I activated the Overview effect with a projector, the effect was shown in both outputs as expected (since the Unify outputs option is selected). There's no problem when I extend outputs. STEPS TO REPRODUCE 1. Connect an external monitor or projector 2. Choose the "Unify outputs" option to show the same image on both outputs 3. Press Meta+W to open the overview 4. The overview will be shown in the primary monitor, but not in the projector OBSERVED RESULT The projector is not showing the overview effect; only the background image is shown. EXPECTED RESULT The projector should show the overview effect as well. ADDITIONAL INFORMATION Operating System: Fedora Linux 40 KDE Plasma Version: 6.1.3 KDE Frameworks Version: 6.4.0 Qt Version: 6.7.2 Kernel Version: 6.9.12-200.fc40.x86_64 (64-bit) Graphics Platform: Wayland Processors: 12 × Intel® Core™ i7-10750H CPU @ 2.60GHz Memory: 15,5 GiB of RAM Graphics Processor: Mesa Intel® UHD Graphics Manufacturer: LENOVO Product Name: 82CG System Version: IdeaPad Gaming 3 15IMH05
Cannot reproduce in current git master. When I connect an external screen (in my case a 1080p HDMI monitor) and select "unify outputs", Overview appears on both screens as expected. Assuming it's fixed in Plasma 6.2, but feel free to re-open this if you find that it's not fixed for you after upgrading to Plasma 6.2. Thanks!

I tested today with the latest Dev edition of KDE neon (built on Aug 18 - Plasma 6.2) and the issue persists. The overview does open on both screens, but the windows are shown only on one of them. Here is an improved set of steps to reproduce the issue: 1. Connect an external monitor or projector 2. Choose the "Unify outputs" option to show the same image on both outputs 3. Open some application windows 4. Press Meta+W to open the overview 5. Notice that the windows will appear only on one of the outputs; they should appear on both, because outputs are unified
It sounds like the original issue was fixed, but there's now a new issue with the *content* not being mirrored as expected. I can reproduce that. We can track it with this same bug report.
