Are you from different planet?
Did you read the install instructions? It says "If you get "Unsuccessful boot read error at 47%", don't worry, YOUR ROM FLASHED JUST FINE."
They recommend CN stable for AOSP roms, I am under Global 12.5 stable. Also for the ones who have adb not working try to update your platform tools and check your windows drivers for your device.
If not mistake and knowing from previous device I use with derp that option when turn off is supposed to kill your navigation gestures, it's intended to be use with other apps that's modified gestures like FGN.Flashed ROM, works very smooth.
One thing I noticed
Settings -> Derp Quest -> Enable navigation bar
When this thing is turned off
Navigation bar is gone, but side gesture does not work (swipe from left / right), only swipe from bottom is working
Not big deal for me, I'll use Edge Gesture
Check the refresh rate and set the preferred refresh rate to either 120 or 90 With minimum at 90Everything is stable so far.
Since I use a lot Twitter (default app) and Infinity for reddit, I can notice scroll performance issues.
Infinity was super smooth on MIUI. Now I see frame rate drops / rendering issues on DerpFest.
Gmail performs same as on MIUI
Scroll acceleration is different than MIUI, maybe that cause problems.
One more thing I noticed, on dark backgrounds, let's say browsing XDA with chrome / brave
Every 10 seconds panel slightly changes background to lighter gray than it goes back to darker gray, screen flicker for 1 second, tried to record this but it's not visible on screen recording.
Not sure if this is related to screen refresh rate or something else.
Effect is similar to True tone display on Macbook, where colors are adjusted based on environment.
