Excel 2016: Characters on a button (ActiveX control) on worksheet look larger than normal with 4K (High-DPI) monitor. It does not happen with 2K monitor.

I see a strange phenomenon, with 4K (3840 x 2160) monitor.
Does someone have the same/similar experience?

Excel 2016:
Characters on a button (ActiveX control) on worksheet look larger than normal with 4K (High-DPI) monitor. It does NOT happen with 2K monitor.
This issue happened after updating Excel 2016(I don't know exact date).
