Windows caption not scaled

This is not a Groupy issue as Groupy does not alter the caption text or paint titlebars.

It is a known defect in the Windows 10 OS where sometimes the OS caption font will be sized stupidly small when you have a high res monitor and have changed scaling / resumed from sleep sometimes / other random events.  The fix is usually to reboot.

Thanks for reply. I'll reboot later and check.

I have exactly the same issue. Not sure if it is a coincidence, but it started happening since I installed Groupy last week. 

I my case reboot resolve the problem. So far after wake up from hibernate i don't have problem with caption size.
