I guess my previous post wasn't clear enough. ALL Windows builds up to Version: 0.19.24267 (Git) did not exhibit this bug. Side note: I design Stylesheets for other Qt 5.15 apps and they don't exhibit this bug. I don't think it is QTuwestoehr wrote: ↑Fri Apr 02, 2021 9:54 pmbug on all Pre Releases up to Version: 0.19.24267 (Git) which was QT 5.12.5
Confirmed. So the question is not if it is a Conda build or a LibPack build and since it occurs with Qt 5.12 and 5.15, it is most probably not Qt.
What was the last Windows build without the bug? Then I can do a bisect since it seems that a change in FreeCAD's code causes this.
