Partial refresh for Waveshare 12915?

[RicoElectrico]

As in the title, when I use waveshare2in13b_v4 partial refresh doesn't work...
It's a B&W display.
using v2.9.5.3 on RPi Zero rev1.2 (non-W) with rtl8192
The pwning feature does work nicely, though.

Because 2.13b is a 3color display. You should use waveshare_4 as display type I think.

Thank you. I played with these options as it appeared dead with ws4 but it just needs 15 s after initial refresh for something to happen.

And, the display is pretty nice, ghosting is barely visible. Though I will also get 3color from AliExpress that I ordered earlier by mistake. Guess will connect that one to esp32 and Xiaomi scale for some weight chart :D
