Is this a unicode Delphi version you use or not and do you use the latest version of Delphi?
Hello, I forgot to mention I use the latest TMS Component Pack, 126.96.36.199 and delphi XE8.
I cannot reproduce this. Do you have details / step by step info how to reproduce?
Also, it looks like your first app does not have runtime themes enabled. Does it help when you enable runtime themes?
As I found this behaviour only in one huge programm, I could not reproduce it with a new programm.
Did you verify the font used in the grid?
The font was MS Sans Serif!
