I'm on MIUI 12.5.4 Global Stable (Never flashed xiaomi.eu or any other rom)

Can I just flash DerpFest? Or I need to switch to xiaomi.eu or CN stable?

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."

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

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.

Everything 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.

Check the refresh rate and set the preferred refresh rate to either 120 or 90 With minimum at 90

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.

I had the same problem on LOS and EvolutionX. On DerpFest, I no longer see this problem. I just force refresh rate to 120Hz. And automatic brightness is more fluid with DerpFest (imo)

First day/night of use.
It can be daily use at the moment. Really.
Everything is smooth. Highly customizable. No random reboot, no problem with the screen.
Only 2 apps doesn't work : Roborock and Paypal

Magisk/safetynet OK and GPay OK

1 "problem" but i will see in 1 week : 9% battery drain during the first night.
Wifi / 4G / BT ON / 120Hz forced.
No indication on battery drain. Gsam is now running to find the "problem"

    Hey, so I'm loving DerpFest and there are practically zero bugs, but one big issue I found is that people have told me that they can hear themselves in regular calls, VoIP calls, and social media app (e.g. Telegram, WhatsApp, etc.) calls, especially on speaker mode (less noticeable on handset mode). I did some research and found out that this is a common issue with AOSP ROMs and Xiaomi dual mic phones, since the AOSP ROM does not correctly use the two mics for noise cancelling. Has anyone else experienced this on LOS, SSOS, DFOS, or any other AOSP ROMs on the Mi 11? I looked into editing /vendor/etc/sound_trigger_mixer_paths.xml as suggested in the Poco F1 echo fix XDA thread, but I don't think DEC7 and DEC8 are the correct dual mic IDs for this device. If any devs can figure this out, I'd be happy to buy you a 🍺 for your help in making AOSP truly perfect on this device with this one important fix.

    I'm facing some issues with the Google Assistant, as it shows 'This feature is currently unavailable for this language" whenever I try to enable 'Hey Google and Voice match'.

    My current device language is English (UK) altough I'm facing the same issue with Spanish (Spain). Any ideas?

    Also, as other users have mentioned, I believe that the microphone volume is quite low (eg. Whatsapp voice notes)

    Everything else works pretty good. It's a daily for me.

    Hi guys! Finally I've managed to flash DerpFestOS. I used TWRP to change the slot and flash the ROM. Thanks for all the advices and help.
