If I try to use a build of kwin from the git master, or from the Neon Unstable version, the blur effect is no longer working. Windows using 3rd-party decoration plugins which have transparency available just show as transparent, without any blur. Operating System: KDE neon Unstable Edition KDE Plasma Version: 5.21.80 KDE Frameworks Version: 5.82.0 Qt Version: 5.15.2 Kernel Version: 5.4.0-72-generic (64-bit) Graphics Platform: X11 Processors: 8 × Intel® Core™ i7-7700HQ CPU @ 2.80GHz Memory: 31.2 GiB of RAM Graphics Processor: Mesa Intel® HD Graphics 630 This works fine in the 5.21.4 release, but I would like blur on the git master to be functional as I am trying to see if I can make some changes to attempt to fix bug 395725 .
I'm also having this bug on KDE Unstable Repos for openSUSE. I tested many decorations that do enable blur on their json, more specifically Lightly and ClassikStyles. Both have no blur in the unstable builds.
Just got 5.21.90 on OpenSUSE and now blur is not working for window decorations for this branch.
Those are binary window decoration. Does this issue affect also aurorae decorations? Can you also post the output of `qdbus org.kde.KWin /KWin supportInformation` please?

Can you also post the output of `qdbus org.kde.KWin /KWin > supportInformation` please? Just tried, and yes it also affects aurorae decorations. Here is output when a transparent aurorae decoration is selected: ~> qdbus org.kde.KWin /KWin supportInformation KWin Support Information: The following information should be used when requesting support on e.g. https://forum.kde.org.

Git commit 2d9e2f0c701fbd57ab6b6584106b54124f52bdaf by Vlad Zahorodnii. Committed on 18/05/2021 at 12:28. Pushed by vladz into branch 'master'. effects: Fix EffectWindow::shape() for X11 windows With the introduction of scene items, the Scene::Window::bufferShape() method was removed as it makes no sense on wayland - a window may have several sub-surfaces, so a single region to indicate the shape of the window won't work. SurfaceItem::shape() returns the shape of a surface. On Wayland, it corresponds to the rect of the wl_surface. On X11, it corresponds to the client window rect inside the frame window, or custom shape region if the client has set one. On the other hand, EffectWindow::shape() wants a completely different thing. If the window is decorated, it needs to return the rect of the decoration. Otherwise it has to return the shape region if there's one. In the future, the EffectWindow::shape() function must be removed as it doesn't fit the item based design. The main reason why we have it at all is because the x server doesn't support translucency, setting a shape region is a (hacky) way to work around that limitation, xeyes is a notable example.

Created attachment 138761 [details] Screenshot showing how blur is not working on the titlebar Issue still exist on Plasma 5.21.90, coming from KDE repos for openSUSE Tumbleweed (not the Unstable repos). I just updated from 5.21.5. See attachment for screenshot
> Issue still exist on Plasma 5.21.90, coming from KDE repos for openSUSE > Tumbleweed (not the Unstable repos). Judging by https://build.opensuse.org/package/revisions/KDE:Frameworks5/kwin5, 5.21.90 packages were built 10 days ago. The fix landed a few days after that.
