Summary0003673: HIDPI related bug where text doesn't fit grey box in "Documents" when the software starts.
DescriptionHIDPI is more and more used with > 1080p monitors like 4K. It basically downscales the resolution without actually lowering the monitor resolution. It results in crisper image without the tinyzation of everything on a small but high resolution monitor.

Best explained here:

QT5 actually supports HIDPI quite well and it will make FreeCAD usable on workstations using HIDPI (at last!) :) The problem(s) that remain(s) (Maybe I'll find more later) is in the Start page "Document" tab. Each thumbnail is in a gray box with text underneath. The text doesn't fit in the grey box so it makes the welcome to FreeCAD exeperience a bit frightening.

Steps To ReproduceUse hidpi with a 4K monitor. For me it's easy to do with POP!_OS which derivates from Ubuntu. You just go in gnome settings->Peripherals->Monitors, Enable HIDPI and scale to 200%.

I used the FreeCAD_pre AppImage.

This isn't only restricted to "documents". Here is a screenshot of my start page with a HiDPI scaling of 250% on V0.17 on Windows. Notice that not only the text doesn't fit in the boxes, but also the background is not stretched to fit the window

A few more instances of places where text or images don't fit correctly with HiDPI scaling
