Bug ID: 454453
Summary: Window decoration Blur effect does not work with new
setBlurRegion() API on 5.24.90, but always worked on
git master
Product: kwin
Version: 5.24.90
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: effects-various
Assignee: kwin-bugs-n...@kde.org
Reporter: k...@paulmcauley.com
Target Milestone: ---
I have implemented the new setBlurRegion() API for my C++ window decoration
(https://github.com/paulmcauley/classik). This (mostly
https://bugs.kde.org/show_bug.cgi?id=453229) works fine on the git master (and
has for a month or so now), with a blur effect that matches the window shape.
However, when I enable transparency and blur in my window decoration (this
simply calls setBlurRegion() with the window shape) on the 5.24.90 beta I do
not get any blur at all, just transparency.
I have removed the "blur":true line from my .json file (as done by Michail
Vourlakos for Aurorae) . Readding "blur": true to the .json enables blur again
on 5.24.90, but with the kornerbug that the new setBlurRegion API was designed
to fix (https://bugs.kde.org/show_bug.cgi?id=395725).
