Sorry, I did not yet have the time to check if this is an issue with the current version of the display library. Just as a first thought, so I can at least give some input: Did you try an older version of GxEPD2 from around the time I released my project? Also: Did you install the library manually or from the Arduino library manager? (So I can try it myself when I find some time.)

Turns out this did not compile on windows, I compiled it without issues on arch!

Thanks for the feedback and sorry that I did not check it. Since my only Windows machine is purely used as a drum computer, I cannot really say anything about this problem, but I will leave the issue here in the hope that someone else can shed some light onto this problem. In my experience Arduino libraries are usually not too picky about how they are included and on which OS they are compiled (after all it's a cross-compiling process in any case).
