Colors invert randomly about infinitime HOT 7 OPEN

This has happened to me, but I know a way of reproducing this issue.

You need to turn on lower wrist to put the watch to sleep and go to the paint app, then just keep holding the screen and lower it until the screen turns off, and after you turn the screen on again, all the colors are inverted, I have attached a video showing it.

It may have something to do with the issue #1992

yea i'm really not sure why this happens, and i've seen it occur multiple times while working with the display driver. My best guess is there is some issue with how we are writing to the LCD control register, and accidentally (perhaps an overflow) writing the command to invert the colors. I'll have to do some investigation to be sure though

I have seen this happen. Would a (temporary) work-around be to assert the flag to not invert colours when accessing a screen, e.g. watchface / info.

I can reproduce this as well. This issue seems to also be the roots of the issue we're experiencing with #1869 (#1869 (comment)). There is some kind of issue with how the display is being controlled (SPI), which is causing unexpected behavior with the display

Having a consistent repro is amazing, thanks!!!!
