Hmm, activities are unsupported on Wayland. Did you mean that the default virtual desktop switching animation (the slide effect) is broken on wayland? (In reply to Vlad Zahorodnii from comment #1) > Hmm, activities are unsupported on Wayland. Did you mean that the default > virtual desktop switching animation (the slide effect) is broken on wayland? yes, sorry for the bad wording. I mean the slide effect. Hmm, could it be the gap between virtual desktops? Have you tried settings gap values in the kcm of the slide effect to 0? setting* no, its not that. but i did set to 0 the gaps on that effect. I am trying to upload a video that I did with the mobile phone to youtube to show what happens. I will post the link here as soon as it is uploaded. here it is: https://youtu.be/sVQB_JWcOr4 sorry for the bad quality, hope you can understand it ( see the corners disappear (turn black) while in the effect ) I can't reproduce this on current master branch. (In reply to Thiago Sueto from comment #7) > I can't reproduce this on current master branch. I just updated opensuse git packages and its still present. I will test it again tomorrow. From the video, it looks like the rendering issues are present only on the secondary monitor, right? Are screen edges clipped when the blur effect is disabled? (In reply to Vlad Zahorodnii from comment #10) > Are screen edges clipped when the blur effect is disabled? Nailed, that is it ! without blur, it doesn't clip them ! After a bit more thorough look at paintSimpleScreen(), I haven't found anything suspicious. Furthermore, it looks like only parts that contain old desktop contents are clipped. It can be easily verified by reducing the animation speed. My assumption is that plasma creates a new texture during the switch animation and renders only desktop contents on the new activity. The area that contains the old desktop contents is left uninitialized. A possibly relevant merge request was started @ https://invent.kde.org/plasma/kwin/-/merge_requests/318 Thanks ! Vlad, I will test and report back as soon as opensuse git daily packages release the daily package with this fix ! Git commit 3e1443e003bf5fc0e20dd7de49505fd0227bdce4 by Vlad Zahorodnii.

Pushed by vladz into branch 'master'. wayland: Don't force a bpp of 24 for desktop windows plasmashell provides the compositor buffers with an alpha channel and without indicating the opaque region. Given that, kwin forces a bpp of 24 for desktop windows to improve performance. Unfortunately, there are legit cases where plasma may attach a buffer that is not fully opaque, for example when switching between activities.

[shell] Set DesktopView to black when no contents are loaded This is better than the ContainmentView default of clear as it means we don't get garbage from the root window.
