FMX app halts on Windows 10 with a workstation GPU

I just tried my FMX app on a Windows 10 with a workstation graphics card (Nvidia P600), and it would not run at all.
When executing it shows up in the taskbar, but in the "not responding" state, and after a few seconds it disappears - without showing anything on the screen. No error messages.
I have thousands of Windows users and no one have reported this error, so this is so far just an internal finding that might or might not be a big issue.

Anyone having experience with FMX and workstation GPUs?

What I have tried so far:
* When setting the Windows compatibility mode for the .exe to Win7, it runs fine.
* On the same computer it runs fine with a traditional graphics card (everything else unchanged)
* An empty FMX app runs fine too (my app uses lots of custom components with custom drawing, including custom TTF fonts)
* When setting GlobalUseDX := false, the app runs, but I get an error message when painting custom components.
