I flashed it on xiaomi.eu stable 9.1.2.0 with 3DTouch disable before flashing and everything work flawlessly, try to flash original kernel (extract boot.img from your original ROM) and disable 3DTouch and flash this kernel again, maybe it can help solve your problem.
ahh, thanks, will try it again.
Do you find WiFi is slower when using this kernel? it could be my router is acting up but I couldnt get good speed compared to other phone in same room
