SUMMARY STEPS TO REPRODUCE 1. Open System Settings > Desktop Behavior > Desktop Effects 2. Open the filtering dropdown menu (between the search bar and "Get New Effects") 3. Attempt to click / "check" the checkboxes OBSERVED RESULT The checkboxes don't become checked, but their background color changes to blue (default Breeze theme). The filtering operation indicated by their description seems to apply. EXPECTED RESULT The checkboxes should become checked when clicked / "checked"
They do actually get checked, but so does the background. Which is weird.
Porting the KCM to QQC2 should fix this issue, as well as Bug 396725. I'm working on this.
Here's the patch: https://phabricator.kde.org/D17928
Git commit d28827626931ed9f8fbfd618bbdcdf3fdce6a5e6 by Nate Graham. Committed on 06/01/2019 at 23:09. Pushed by ngraham into branch 'master'. [kcmkwin/compositing] Port Effects KCM to QQC2 Summary: This patch ports the Effects KCM to QQC2, which yields the following benefits: 1. General performance enhancements of only using QQC2 rather than a mix of 1 and 2 2. Some code simplification is possible 3. Improves the appearance of the checkable menu items in the dropdown menu, fixing https://bugs.kde.org/show_bug.cgi?id=402701 4. Improves the appearance when using a fractional scale factor, fixing https://bugs.kde.org/show_bug.cgi?id=396725 5. Fixes the incorrect size when opened from `kcmshell5` Along the way, two visual changes are introduced as a by-product of porting: 1. The scrollbar is inline, so it overlaps some of the buttons in the content. This is somewhat undesirable, but adopting a Kirigami scrollview would fix this. 2. The button that displays a dropdown menu no longer has a downward-pointing arrow to indicate as such. This is not my preference, but there's a benefit to being consistent, and eventually we could can change this in one place to impeove the appearance of buttons that display dropdown menus everywhere in one fell swoop.
