Thanks a lot for the information at the time I have the global beta, and in full screen mode, I have some lag especially in the swipe for recent apps.. I'm waiting for the bootloader release.. Some other day and I put on the Xiaomi.euAbsolutely no delay on my max 3. I'm running 8.11.15 rom. You may try dirty flash then re-install rom again, it's may help.
8.11.1 didn't have that problem, but I don't wanna go back 2-3 builds... and I installed global beta just to check out, it happens on global too, I doub't its Xiaomi EU related
