How to change the font size of Orbbec Viewer in Arm64

Hi
How do I change the font size of the Orbbec Viewer in arm64(ubuntu) with the Nvidia Jetson AGX Orin development kit?
As you see the picture, the font size is too small to see. Please help me to enlarger/setting the font size.

Hi Nathan
Thank your tips.
It helps, but not much.
My screen has a resolution of 3440x1440. The font of K4aviewer is still very small compared to other apps (such as Chrome).
I opened the style editor of K4aviewer, but the values can not be changed.
Any other ideas?

Are you saying K4aviewer? K4aviewer is the design from Microsoft, we won’t be able to change that.
