Scroll behavior with Touchpad/Mouse is not smooth - working fine with touchscreen #528

Open NilsRo opened 7 months ago

NilsRo commented 7 months ago

Steps to reproduce

Scrolling with touchpad or mouse is not smooth, there are erratic jumps of the screen. Touchscreen scrolling is very fine in comparison.

✔️ Expected Behavior

Scrolling with touchpad should show the same behavior than with touchscreen.

❌ Actual Behavior

Scrolling with touchpad jumps. You can see that in the first half of the video and in the second with touchscreen which is smooth.

Other Software

See that behavior on an Dell 7320 Detachable (like a Surface) with i5 1140G7 and 16Gb Ram and also on a Dell 7706 2in1 with i7 1160G7 and 16Gb Ram. But as scrolling is fine with touchscreen it should be not related to the performance of the hardware.

I'm no expert on this but I believe this is just the subsystem mimicking touch scrolling to ensure compatibility with apps that don't directly support mouse inputs, which would explain why it is smooth on touch. This would mean that this isn't a bug but rather a feature and removing this may disable scrolling in certain apps that haven't been developed with keyboard/mouse functionality in mind.
