Summary0003130: FreeCAD 0.17 Qt5 bugs with external display
DescriptionWhen connecting an external display (Dell U2913WM) with a macbook Pro 15'' TouchBar (with retina display) some buttons icons are rescaled incorrectly and what is more important, there is a big offset from your mouse position and where the 3D window thinks you are in "screen space". You can see both problems in the attached screenshot.

Steps To ReproduceConnect laptop to external display and open FreeCAD

Confirmed on both accounts: Icons shown above are scaled up and draft snap has an offset from the mouse location. Tested on 1080p display using the version below. Somewhere some scale factor is not updated when moving to a different display.

It probably should be separated into two issues (0003130 that is). f3nix fixed the 3d viewer issue, but the icon scale problem hasn't been fixed yet.

I have just tried it out and, without knowing if it was a partial solution or not I can say that:
  • "file" and "view" toolbars still are "magnified" in the external display (if I move FreeCAD window to the HDPI macbook Pro screen it shows correctly)
  • clicking and drawing now works correctly, there is no offset but:
  • using "box selection" you get the "offset bug" when inside the Sketcher and only when FreeCAD window is in the HDPI macbook Pro screen (it works fine in the external display)

Can anyone test with a higher version of Qt5 ?
