Really? All of my dev tools support scaling.
Intellij, Cygwin, Ubuntu VMs (DPI scaling worked well in vmware at least), VS Code, VS proper, sublime, idle, cmd, cmder, IDA, Tableau. I can't think of a single application (except for Eclipse) which I noticed not scaling well.
RStudio on Windows (fixed now, and some workarounds) - https://support.rstudio.com/hc/en-us/community/posts/2065421...
