Description pawel.veselov 2025-06-22 22:14:50 UTC 
SUMMARY

After upgrading to 6.4.0, configuring mouse clicks with other than "... and pass click" options makes them unusable for Plasma components and pop-up menus.

STEPS TO REPRODUCE
1. Configure (for example) left click for Inactive Inner Window Actions without "...and pass click", apply configuration
2. LMB on any of : Task Manager, Application Launcher, System Tray - no reaction to click
3. LMB on a pop-up menu item, i.e., in Gwenview - no reaction to click

OBSERVED RESULT
No click reaction for cases outlined in "Steps to Reproduce"

EXPECTED RESULT
Normal click reaction

SOFTWARE/OS VERSIONS
Operating System: Fedora Linux 41
KDE Plasma Version: 6.4.0
KDE Frameworks Version: 6.15.0
Qt Version: 6.8.3
Kernel Version: 6.14.11-200.fc41.x86_64 (64-bit)
Graphics Platform: Wayland


ADDITIONAL INFORMATION
Same problem with Flatpak apps that use Qt 6.9.0, btw.
Apologies if I'm filing this against a wrong category/app, the best I can understand this is Kwin's responsibility, as the behavior is controlled by Kwin.
Pleaset LMK if there is anything I can help with.

Fix Window::mousePressCommandConsumesEvent() for "activate" action

Amends 87bb2447e5328a5e6f4d066fcfea5ff38a02139d.

According to the boolean algebra rules, if the `a || b` expression is
negated, the result will be `!a && !b`.

In the prior version, the MouseActivate option used to correspond to
`isActive() || !rules()->checkAcceptFocus(acceptsFocus())` so following
the boolean algebra rules, the `||` operator should be changed to `&&`.
