[9.0a] Dialog box scaling 300dpi can't fit Config. on 1080p

[MaxX]

The bug, found by russian user in the web.
I can reproduce it too.

Win 7 SP1 x64 + classic theme
TC 9.0a (both 32 and 64 bit)
Screen resolution 1920x1080

Go to TC -> Configuration -> Fonts -> Dialog box scaling.
Then set 250 dpi (or more) and press Apply.
Now Ok/Cancel/Help/Apply can't fit on the screen to be shown.
No turn back.

When you already have pressed Apply, Cancel won't help because settings are already saved. What will help is setting another DPI value and pressing e.g. Enter key (which acts as OK).

But I agree that TC shouldn't allow setting too high DPI, it should limit it to some constant value, or to some value that depends on screen height.

BTW I still see OK/Cancel buttons with 250 DPI on full-hd monitor (though I'm using classic theme).

BTW2, it is funny, up/down control is realized as a scrollbar component and it has large scrolling area on high DPI!
I don't really think that up/down control is useful for combobox (especially when scrolling down increases the value) while in other places scrolling with mouse wheel would be nice (in tabstop settings). Unfortunately Delphi has no standard up/down control while it is a standard Windows component.

I can still reach the dropdown combobox even at 300dpi, and then select 96 and press ENTER to make the box smaller.

1. No "Ok/Cancel..." buttons
2. Left side text becomes broken

When you have only touchscreen (no keyboard/mouse), there's no way back to set 96.

Try 300 dpi (for 1080p) to see.

The bug is not in dropdown combobox. Just look bottom side of the screenshot. There's no button bar "Ok/Cancel...".

Windows dialogs also have this problem on low resolution monitors... If a dialog doesn't fit on screen, you can't click cropped controls.

Is it Windows' bug too?

[MVV]

Well, I never use Windows font scaling just because most WinAPI GUI dialogs look ugly with it, and TC too because Delphi uses standard Windows controls... Perhaps you use both TC scaling and Windows scaling because I see no cropped text in list of configuration pages even when I set TC scaling to 500 DPI.
I don't know if it can be properly tweaked, but with Windows fonts become larger while most metrics aren't changed (checkbox size, listbox item height, scrollbar button height etc), and this causes huge mess.

I think it's because of the higher font size of 24 that probably adds to the scaling.
