Incorrect UI scaling

[dromer]

At the moment the default size is rather huge, which makes the entire UI very difficult to view and navigate.
For the graph we can zoom out, but the rest of the UI is still very bulky this way.

Please add an option to change the default font size, so we can adjust the way the entire UI gets sized.

This may be a bug, can you provide a screenshot?

[dromer]

Sure:

I tried on latest Ubuntu X11 and got the same behavior. Linux Mint X11 though had no problems. What distro and window system are you running?

[dromer]

Debian 12, X11 and Fluxbox.

Not having any fancy Hi-DPI going btw.

The scaling is set based on Xft.dpi, maybe it's not set correctly in your setup. As a workaround you can run coppwr with the WINIT_X11_SCALE_FACTOR environment variable set to your display's scale factor, or whatever works best. For example WINIT_X11_SCALE_FACTOR=1 coppwr

[dromer]

Indeed WINIT_X11_SCALE_FACTOR is not set. If I set it to 1 everything looks good!

So maybe default to 1 when the env-var is not used?

[dimtpap]

It may be a bug in winit, the windowing library used by coppwr, that should be reported. I'll try messing with Xft.dpi to see if it's respected. If it is, it's an end-user X11 configuration issue, otherwise it's a bug in winit

[dromer]

Hmm, I don't think expecting unused envvars to be set makes a lot of sense.
This is actually the first time I hear about this one.

Can you check with the winit devs then? This is a bit out of my league (I'm just a poor user ;) ).

Yes, winit falls back to a manual calculation of the factor based on the display's properties if neither Xft.dpi nor the env var are set. Thanks for linking it
