Blur missing when window is smaller and then maximized

[D3SOX]

Reproduction steps

• Have a window that is not maximized and force blur enabled
• Resize it to be relatively small (needs to be a smaller geometry than your monitor)
• Maximize that window

Now the area that was not in the geometry of the whole monitor isn't blurred.

Could you provide a video? I'm not able to reproduce this. What happens when you manually resize the window to the size of the screen?

[D3SOX]

No it needs to smaller than the screen, I can provide a video later

It happens for me as well with the Obsidian app. Here's a video: Screencast_20240310_195654.webm

What happens when you manually resize the window to the size of the screen?

On manually resizing it works as expected: Screencast_20240310_200007.webm

Okay, I've managed to reproduce the issue with Obsidian.

Should be fixed. Check if the issue occurs on the develop branch. Only applications with client-side decorations (excluding GTK apps) seem to be affected.

Thank you @aksh1618 for providing the screen recording. I'm gonna test the branch and report back :smiley:

I needed to restart KWin (which is a little annoying on Wayland because there's no full session yet) but then it worked fine on the develop branch :rocket:

Here is a simple oneliner for Arch users to build the develop branch

git clone https://aur.archlinux.org/kwin-effects-forceblur-git kwin-effects-forceblur-develop && cd kwin-effects-forceblur-develop && sed -i '/source=/c\source=("$pkgname::git+${url}.git#branch=develop")' PKGBUILD && makepkg -rsifc

Fixed in v1.1.1.
