Hello Boki,
in NextGrid6 scaling of header font is good if the header font is predefine without style fsbold.
I can switch the header font style at runtime with expected result.
But when the header font is predefine with style := [fsbold] the scaling in HiDPI fails.
Changing the header font style back to style := [] has no effect for scaling until replacing nextgrid with a new instance.
Best regard
Stefan
