GDEH0154D67 eink screen working worse after update from tags/5.1 to current release/v5.1 branch (IDFGH-13417)

Not sure how you set up the SPI driver for the e-ink display, but we have a similar driver for the SSD1681 e-ink driver IC here, maybe you can have a try?
The cause was the way I include arduino core into the project, still not resolved, Idk if this is an issue with esp idf or arduino core now, if its just arduino core fault then this can be closed I think?

Reverting back the idf version fixes it, but that's not a solution
Were there any changes to SPI in between those releases? What changed? I can't find it.
