Hi Mariusas,
Thanks for the detailed request.
This affects only people running old versions of Windows 10 (my Windows 10 test machine doesn't have this issue for example).
This will be fixed in the next version of Qt, which is not yet released.
But for now I compiled the latest source code of Qt for Windows which should solve this issue and made it available for you to download. Just get the Qt_fix_old_win10.zip file and overwrite all the files. You should do the same for the full version if you have it.
Hopefully this works for you!
