Bug ID: 452208
Summary: Moving windows with super+lclick is allowed when a
context menu is open on Wayland
Product: kwin
Version: 5.24.4
Platform: unspecified
OS: Linux
Status: REPORTED
Severity: normal

SUMMARY
When a context menu is open in an application, using super + leftclick to grab
and move the window is blocked on X11. In Wayland, this is allowed. This leads
to a significant amount of breakage with window focus and painting:
- The menu remains open, and does not move relative the application, however,
its click targets do move relative to the application (though when moving the
cursor over the context menu itself, does have correctly lined up targets).
- This results in some strange issues when painting the application as
focused/unfocused. If the cursor is moved such to move from one selected menu
to open another, the window's application area is painted unfocused, but the
titlebar is painted focused. The application is treated as unfocused (I've
noticed that when a context menu is opened for an unfocused window in Wayland,
the context menu gets window decorations and opens in the center). Sometimes,
when refocusing the window, it is not repainted as focused, though buttons are
when hovered over. These buttons are also not repainted as unfocused when the
window is unfocused.
- The broken painting behaviour cannot be replicated on X11 because when a
window has a context menu open, super+leftclick to drag the window is not
allowed.
- This is also broken in KDE's System Settings application, which uses a button
to create a menu rather than a menubar.
- I have also noticed that opening the menu in System Settings on X11 paints
the application area of the window unfocused. This is not replicable in
Dolphin, which has a similar burger menu, though its created menu seems to
suffer from Korners (the corner rendering seems to differ from other menus).
This issue in Dolphin seems to be a distinct bug, present using Wayland and X11
so I will report a separate issue for it.
I am not sure exactly how many bugs exist here, or how to categorise them. **I
suspect that most/all of the breakage here is caused by super+leftclick to grab
being allowed when a menu is opened on Wayland.** This likely breaks some state
resulting in focus and painting issues.
A lot of this was hard to describe and likely not explained well, so I'd
encourage some experimentation to see the broken behaviour. I will submit
another post with images showing the broken behaviours.
I am not sure where this bug should be filed so I have placed it in
kwin/general. Please move if this is not appropriate.
