Bug ID: 502276
Summary: Trying to rotate camera in blender (with middle mouse
button) when "Press middle mouse button and move to
scroll" option is checked results in multiple
dysfunctions
Classification: Plasma
Product: plasmashell
Version: 6.3.3
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: minor
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Target Milestone: 1.0
SUMMARY
"Press middle mouse button and move to scroll" option interfears with the
normal functioning of blender, specifically instead of rotating the camera as
it should it causes the camera to zoom in or out. In addition when trying to
use the middle mouse button to rotate in blender it results in the mouse wheel
not functioning normally in all programs afterwards until display-manager is
restarted. After causing the bug in blender when scrolling in any program
afterwards and then scrolling in the opposite direction the first scroll in the
opposite direction will not register. The bug presists until display-manager is
restarted even after blender has been terminated.
STEPS TO REPRODUCE
1. make sure "Press middle button and move mouse to scroll" is checked in
system settings under mouse options
2. open blender (https://www.blender.org/ or just install it with your package
manager)
3. hold middle click (the scrollwheel button) to try to rotate the camera and
move the mouse forward and back. This will result in the camera zooming in and
out instead of rotating as it should.
4. Now close or tab out of blender and open firefox or your preferred browser
or anything that you can use the scroll wheel to navigate up and down with
5. Scroll down, then scroll one tick upward, that tick should be ignored and
not register for some reason. Subsequent ticks upward should register.
6. Scroll down again after having scrolled up, the first tick of downscrolling
should not register and be ignored for some reason.
OBSERVED RESULT
One tick of scrolling is always ignored when switching scroll directions and
trying to rotate the camera in blender results in zooming instead
EXPECTED RESULT
Rotating the camera in blender with the middle mouse button should work without
issue and should not result in a subsequent system wide screw up of the mouse
scroll wheel.
