Smooth panning > setting enabled > slammed into the lowest zoom possible
Hi! I searched for middle scroll and didn't see this issue come up.
I just updated to the opt-in for Steam Deck to access new Plasma 6 settings
like this mouse option and am encountering technical issues with the
implementation. The mouse behaviour on Linux is a concern for trying to get
more into a non-Windows system (I don't see a usecase for the pasting, myself,
as I like the clear control of CTRL-C CTRL-V & usually just end up pasting
random nonsense strings into Discord by mistake previously).
KDE Plasma is a lucky and appealing first choice in that regard, as your design
philosophy goes against the common hostility I've seen elsewhere from people
used to using their computers a different way.
Thanks for working on implementing an option for this common preference outside
long-time Linux users!
SUMMARY
The [Press middle button and move to scroll] setting introduced in Plasma 6
breaks navigating video games, as it overrides basic camera controls. This
override of apps is universal, as can be seen in also replacing the
click-scroll of Firefox (no directional box showing up in the clicked location
anymore). Upon testing I see it also breaks panning around your workspace in
apps such as GIMP. A general issue with the setting.
STEPS TO REPRODUCE
1. Middle-click and pan around normally.
2. Enable the setting in [Mouse & Touchpad]
3. The OS now overrides game controls and doesn't let you pan the camera at
all.
OBSERVED RESULT
Instead of smoothly going along with your mouse movements as desired, it
freezes up in place and frenetically zooms in and out on the exact spot your
mouse was.
EXPECTED RESULT
Not overriding how the mouse is meant to be used in a given application.
Without taking these into account the only remedy would be to open System
Settings for the mouse every time you were to use a different application.
Discord? Open it and enable. Game? Open it and disable. And so forth.
