Why it is categoried as warning? I gave it as an example rom that is on the same base but animations there are close to original china rom. Maybe you changed something in config files or in build.prop file that impacted on animations. Do you know what app for windows can extract img from china...
Animation are not smooth like on the china rom or on mi room rom. Maybe one of your modification breaks animation smoothing. All three roms use the same kernel.
Are you using the newest firmware in your rom?
After one day without reboot mi8 started lags. After reboot it returned to normal fluid work.
Edit: after disabled Bluetooth I have to reboot phone. I cannot enable it again without that.
I'm not asking about ETA of xiaomi.eu but about news about new China rom. I cannot find any information about that.
I know that xiaomi.eu is based on China rom, so without new base (China rom) team cannot do anything
