Powering off doesn't fully update the screen to poweroff.png

[tbethe]

Describe the bug: When I turn off my reMarkable, the screen keeps the last screen. Uninstalling rm2fb fixes the bug.

Steps to reproduce the behavior:

1. Turn on reMarkable2
2. Turn it off. 

Expected behavior The screen should be updated to show the poweroff.png before actually powering off,

Version Information:

Device: [reMarkable 2]
OS: [2.5.1.45]
rm2fb Version [1.0.0-7]

It turns out the same thing happens when the tablet goes to sleep. When it goes to sleep I see a mix of the last screen I was on, and the sleep screen.

Sounds like a timing problem. Perhaps this will be resolved by #44 ?

@tbethe have you had a chance to test this since the change was merged? I would expect that this is now resolved.

I am not using oxide/rm2framebuffer anymore.

I'll see if I can make time to try it out, but I cannot remember what my setup was from 2 years ago.
