When choosing large font sizes in the Windows control panel (like 125%, or 150%) then there are problems in a VCL application, every time something has been set pixelwise.
TStatusBar.Panel. I have set its width so that it contains exactly one label, now with big fonts the label "overflows". Same problem with other components.
Some new laptops from Dell ship already with 125% as default setting, so while in the past this problem was quite rare now it is really important.
What can be done to overcome this problem?
