SUMMARY
I have a ElanTech multi-touch touchpad with two-finger vertical / horizontal
scrolling support. I use Synaptics X11 driver.
If a text file with lines longer than the view frame of KTextEditor is loaded,
I encounter a weird diagonal scrolling behavior when I scroll vertically. I
don't mean small amounts of horizontal scrolling caused by hand.
I don't encounter this problem with other Qt and GTK text editors.
Videos of Kate, Geany and Notepadqq when I am scrolling using the same gesture
/ hand position is attached.
STEPS TO REPRODUCE
1. Load a text file with long lines or resize the window of a editor which uses
KTextEditor (Kate, Kwrite etc.)
2. Try scrolling vertically
OBSERVED RESULT
KTextEditor scrolls both vertically and horizontally
EXPECTED RESULT
KTextEditor should scroll vertically a negligible amount of horizontal
scrolling is acceptable.
