FreeCAD trackpad controls: Dragging seems laggy #18746

Open oliof opened 7 months ago

oliof commented 7 months ago

Cura Version

5.7.0-beta1

Operating System

POP!_OS Linux 20.04

Printer

Any

Reproduction steps

  1. Turn on FreeCAD touchpad style navigation
  2. Try Dragging the view around holding down the shift key

Actual results

Dragging seems to follow the mouse at maybe half speed

Expected results

Dragging should be at a more natural speed

Here is a screen cast video of the issue. As you can see, dragging is slow while rotating the view is tracking the mouse movement more closely. Screencast from 03-27-2024 05:19:20 PM.webm

Hm, doesn't reproduce when I'm using windows. I'll ask one of my linux-using colleagues to take a look at it.

oliof commented 7 months ago

I also see that zoom and rotate are fixed on a point and do not center on the mouse pointer as in FreeCAD. Should I file an additional issue for that?

rburema commented 7 months ago

Normally, yes, but I'll just add it to the points to be discussed for now -- we'll get back on if we'd like an additional issue for it.

(There is a separate preference in Cura for 'zoom towards mouse pointer' though. That'd only solve half of it though, if it's even what you want...)

oliof commented 7 months ago

"Zoom Towards Mouse Pointer" makes zooming and rotating with FreeCAD Trackpad navigation selected work as expected; I would suggest to enable it by default when people choose FreeCAD Trackpad navigation to better match expectations.

Also, one more comment: This is ona HiDPI screen, which may be a factor.

nallath commented 7 months ago

I think it might be the HiDPI screen. We couldn't reproduce this on linux & windows with a "normal" screen.

oliof commented 7 months ago

I will try to switch the display to Low DPI and report back.

Alright, I did some more testing, and figured out the following: a) it's resolution dependent. Switching to 100% scaling on a 2256x1504 display amplifies the issue. b) it's not a problem with the new FreeCAD Touchpad mode, I have the same problem with Cura 5.6 and 5.7 in Cura's native navigation mode. c) I tested Cura 5.5 and 5.4 for posterity, and they have the issue as well. So this either is an old issue, or an issue with my OS/X11 setup that crept in some time between.
