[BUG?] Cropped icons

[pablogil]

Hi @pablogil

Can you confirm this is still an issue, when using latest FreeCAD 0.19 DMG?

Give me some days, I don't have the external monitor close to my actual home so I need a few days to check it out.

Hi @triplus,

I can confirm that this is still an issue. I just installed 0.19-19107: the icons look cropped on my external monitor, and they look fine on my main monitor. This is on a Macbook Pro 13" with retina display.

I also had the time to check it out this Christmas and the bug is still present...

This is an upstream Qt issue. A while back we have enabled AA_UseHighDpiPixmaps attribute in FreeCAD to get nice icons on HiDPI displays. In addition there is an icon theme (FreeCAD-default) embedded and used in FreeCAD by default. There needs to be a third ingredient and that is a dual display workspace, where each display has a different scale factor set. If all this conditions are true, the mentioned issue can be observed. Until the issue gets fixed in Qt, and as we won't be turning AA_UseHighDpiPixmaps attribute to off by default, to mitigate the issue i have created a PR, basically i left only one icon (screenshot command) in the embedded demo icon theme pack. No icons from an icon theme will get used on toolbars, hence the issue should be resolved.

P.S. For people using the IconThemes module (not legacy), the issue will still persist in such scenario. Until the issue gets fixed in Qt there is some manual control avaliable:

Run when FreeCAD is located on HiDPI display:

Code: Select all

from PySide import QtGui, QtCore
QtGui.QApplication.setAttribute(QtCore.Qt.AA_UseHighDpiPixmaps, True)

Run when FreeCAD is located on regular display:

Code: Select all

from PySide import QtGui, QtCore
QtGui.QApplication.setAttribute(QtCore.Qt.AA_UseHighDpiPixmaps, False)

P.S. Or just run the last code snippet once and give up a bit more crisp icons on HiDPI display.
