Bug ID: 511029
Summary: high resolution scroll events get ignored
Classification: Plasma
Product: KRdp
Version First 6.5.0
Reported In:
Platform: Neon
OS: Linux
Status: REPORTED
Severity: normal

SUMMARY
Scrolling with a touchpad doesn't work (at any reasonable speed). Honestly I
thought this should have been fixed by BUG:496747 but apparently not. Notably,
this hasn't worked correctly in any Plasma version for me.
STEPS TO REPRODUCE
1. Use a mouse or touchpad with high resolution ("pixel perfect") scrolling
2. Connect using Krdc
3. Try scrolling normally (and slowly)
OBSERVED RESULT
My understanding is only scroll events that seem to cover enough "distance" in
a single event seem get through, making for very slow scrolling (because most
events are ignored) - and no scrolling at all if I don't give it all I've got
and go warp speed with my fingers :)
EXPECTED RESULT
Either:
- Correct modern scrolling
Scroll the correct distance. Works with krdc connected to a windows host, so
this pretty much has to be on krdp.
- Legacy accounting for scroll distance:
Accumulate wheel delta and send a normal legacy 120px (I think?) scroll event
once that threshold has been reached.
