[PD] Scaling problem

Hi,

So the short version of my question is: PD is tiny on my system, what can I do?

I have a Xfce desktop on a small laptop with HD screen (1080). Everything is tiny because not scaled properly, but I can make it okay by changing dpi size. This makes everything okay except puredata... Puredata is still tiny, I'm guessing because of Tcl/Tk. This is a problem because if I just change the font size it messes up all my tidy patches (hundreds of them) plus it doesn't take effect on graphics. The zoom factor is either 1 or 2. 2 is huge. I wish there was some way to do fractional scaling. Do you know a workaround? In gui plugins maybe? (I wouldn't know how to program a plugin to change that), or is this behavior hard-wired to pd? Thanks
