如何为 FMX 控件添加缺失的边框？

Question

I'm currently designing an FMX app with C++Builder. For some reason, when the app is built and launched (it looks normal in the editor), the upper and left border of TComboEdit s are missing. Same for the right border of grids. This is quite unpleasant to the eye, how to change that?

Here is the design-time settings for one of the TComboEdit s:

object SearchLotComboEdit: TComboEdit
  Touch.InteractiveGestures = [LongTap, DoubleTap]
  TabOrder = 2
  ItemHeight = 19.000000000000000000
  ItemIndex = -1
  Position.X = 72.000000000000000000
  Position.Y = 40.000000000000000000
  Size.Width = 361.000000000000000000
  Size.Height = 26.000000000000000000
  Size.PlatformDefault = False
  OnChange = SearchLotComboEditChange
  OnTyping = SearchLotComboEditTyping
  OnKeyDown = SearchLotComboEditKeyDown

I added pictures of what it looks like:

I have the same problem om my computer. The problem is due to the fact that FMX does not paint some controls (eg Listbox misses right border) correctly when your Windows scaling isn't configured at 100%. It probably depends on your screen resolution as well. Try 100%, 125% or 150% scaling and observe if there are any differences.
