STEPS TO REPRODUCE 1. Launch the Cube presentation of windows. 2. Exit the presentation. 3. Try to relaunch the Cube effect, to no effect. The file ~/.local/share/sddm/wayland-session.log is appended the following message: "QuickSceneEffect.source is empty. Did you forget to call setSource()?" SOFTWARE/OS VERSIONS KDE Plasma Version: 6.0.90 KDE Frameworks Version: 6.3.0 Qt Version: 6.7.1 Kernel Version: 6.9.4-gentoo (64-bit) Graphics Platform: Wayland Graphics Processor: AMD Radeon Graphics
Please update to Plasma 6.1.0 and re-test.
Same here on: Operating System: EndeavourOS KDE Plasma Version: 6.1.0 KDE Frameworks Version: 6.3.0 Qt Version: 6.8.0 Kernel Version: 6.9.5-arch1-1 (64-bit) Graphics Platform: Wayland Processors: 12 × 13th Gen Intel® Core™ i5-1335U Memory: 15.3 GiB of RAM Graphics Processor: Mesa Intel® Graphics Manufacturer: LENOVO Product Name: 83A2 System Version: Lenovo V17 G4 IRU
I forgot to mention that .local/share/sddm/wayland-session.log is always empty. Where can I find a log that is filled by the Cube?
These messages seem to be related to calling the Cube: 17:32:30.092 UTC user@1000.service This plugin does not support raise() 17:32:30.105 UTC user@1000.service kwin_scene_opengl: 0x1: GL_INVALID_OPERATION in glDrawBuffers(unsupported buffer GL_BACK_LEFT) 17:32:30.107 UTC user@1000.service kwin_scene_opengl: 0x1: GL_INVALID_OPERATION in glDrawBuffers(unsupported buffer GL_BACK_LEFT) 17:32:30.110 UTC user@1000.service kwin_scene_opengl: 0x1: GL_INVALID_OPERATION in glDrawBuffers(unsupported buffer GL_BACK_LEFT) 17:33:11.668 UTC user@1000.service This plugin does not support raise() 17:33:11.681 UTC user@1000.service kwin_scene_opengl: 0x1: GL_INVALID_OPERATION in glDrawBuffers(unsupported buffer GL_BACK_LEFT) 17:33:11.683 UTC user@1000.service kwin_scene_opengl: 0x1: GL_INVALID_OPERATION in glDrawBuffers(unsupported buffer GL_BACK_LEFT) 17:33:11.685 UTC user@1000.service kwin_scene_opengl: 0x1: GL_INVALID_OPERATION in glDrawBuffers(unsupported buffer GL_BACK_LEFT) 17:33:13.700 UTC user@1000.service This plugin does not support raise() 17:33:13.713 UTC user@1000.service kwin_scene_opengl: 0x1: GL_INVALID_OPERATION in glDrawBuffers(unsupported buffer GL_BACK_LEFT) 17:33:13.715 UTC user@1000.service kwin_scene_opengl: 0x1: GL_INVALID_OPERATION in glDrawBuffers(unsupported buffer GL_BACK_LEFT) 17:33:13.717 UTC user@1000.service kwin_scene_opengl: 0x1: GL_INVALID_OPERATION in glDrawBuffers(unsupported buffer GL_BACK_LEFT) 17:33:13.723 UTC user@1000.service kwin_scene_opengl: 0x1: GL_INVALID_OPERATION in glDrawBuffers(unsupported buffer GL_BACK_LEFT)
Triggering the Cube with Meta-C key leads to the same messages as in the initial posting. 17:40:10.119 UTC user@1000.service QuickSceneEffect.source is empty.

I can reproduce this. It's caused by https://invent.kde.org/plasma/kdeplasma-addons/-/commit/8ac1a311519deefd8991a2673d03ab30a7dd1233. Someone reported the issue during the beta (Bug 486839) and it got fixed with https://invent.kde.org/plasma/kwin/-/commit/84633badc74ca2502bfd33bc4566667eb4bb57ca, which at the time did work for me. But now I can reproduce that it's broken again.
(In reply to Andreas Sturmlechner from comment #1) > Please update to Plasma 6.1.0 and re-test. Did that, the Cube effect behaves the same (i.e. yields "QuickSceneEffect.source is empty. Did you forget to call setSource()?"). The only noticeable improvement is that the "Beta" watermark disappeared from the lower-right corner of my wallpaper.
I did revert my system to Operating System: EndeavourOS KDE Plasma Version: 6.0.5 KDE Frameworks Version: 6.3.0 Qt Version: 6.7.1 Kernel Version: 6.9.5-arch1-1 (64-bit) Graphics Platform: X11 Processors: 12 × 13th Gen Intel® Core™ i5-1335U Memory: 15.3 GiB of RAM Graphics Processor: Mesa Intel® Graphics Here I can evoke the Cube but can't toggle back to the Desktop with Meta-C.
