Bug ID: 524873
Summary: Add new property for "Ignore middle mouse button
scroll" setting
Classification: Plasma
Product: kwin
Version First 6.7.4
Reported In:
Platform: CachyOS
OS: Linux
Status: REPORTED
Severity: wishlist
Priority: NOR
Component: rules
Assignee: [email protected]

Target Milestone: ---
DESCRIPTION
Certain programs such as Blender or Krita use the middle mouse button for
non-scroll actions and do not play well with the Mouse setting "Hold down
middle mouse button and move mouse to scroll". Similar to the existing property
"Ignore global shortcuts", a property that ignores that setting for specific
windows would allow users to use middle mouse scroll for most applications and
automatically disable it for specific applications.
STEPS TO REPRODUCE
1. In System Settings > Mouse, check the box for "Hold down middle mouse button
and move mouse to scroll"
2. Install and open Blender or Krita
3. Try and middle mouse click to rotate / pan
OBSERVED RESULT
Rotating / panning the viewport / canvas does not work or performance is
severely degraded.
EXPECTED RESULT
Rotating / panning works just as well as when the setting is off.
SOFTWARE/OS VERSIONS
Operating System: CachyOS Linux
KDE Plasma Version: 6.7.4
KDE Frameworks Version: 6.29.0
Qt Version: 6.11.2
ADDITIONAL INFORMATION
The interaction between the middle mouse button scroll setting and programs
such as blender seems to be fairly well known:

The underlying input system doesn't seem like a simple fix, but a property to
ignore the setting should work as a suitable workaround.
