Describe the bug
OpenSCAD fails to load with errors:
QWidget::setMinimumSize: (LaunchingScreen/LaunchingScreen) Negative sizes (600,-492131512) are not possible
The system has a 4k display running at 0.5 scaling to make it match a 1080p display on a second monitor.
If the display is set back to 1.0 scaling, OpenSCAD will load and run.
The scaling can then be set back to 0.5 and it operates normally.
After that, OpenSCAD will open normally even with the scaling set to 0.5

To Reproduce
set display to 0.5 and open OpenSCAD

Expected behavior
Should open normall when display scaling is < 1.0

Code reproducing the issue
If applicable, add trimmed down, self-contained code demonstrating the issue.
