This bug happens on all releases from 1.14.4 onwards. You can see that the camera seemilgly randomly snaps when it stops moving. Happens with all possible compinations of raw input, fullscreen and touchscreen mode. Here is a video demonstrating the issue.
This is clearly dependant on software, but I belive a fix is in order as I am not the only one facing this issue.

Thanks for your time, but technically, this is not a duplicate as the other bug is marked as having a workaround by toggling raw input or not using KDE, however this is not resolved by either of those. It is also in fullscreen,

this is not resolved.
