Por lo que veo no has leido lo que pone en el post de la rom.........
TIPS:
1.
No Keyboard, find in Settings Keyboard as was with Hybrid ROM
2.Set animations to .5x or just disable it..
3.Wait for atleast an Hour for ROM to stabilize.. Then Clean ur finger and Display screen and keep swinging the app drawer Left/right and enjoy the smoothness...
