Hi No-jun,

Could you help to dispatch this bug? thanks :P

Comment 4

[No-Jun Park [:njpark]]

[Blocking Requested - why for this release]:
From the video, it's quite noticeable.  And since it's a regression, I'll nominate it as a blocker.

Comment 5

[Blake Wu [:bwu][:blakewu]]

Benjamin, 
Could you have a look? 
Thanks!

Comment 6

[Blake Wu [:bwu][:blakewu]]

After discussing with Benjamin offline, he will check this problem.  
Benjamin, Thanks!

Could you verify the bug again? Because I can't reproduce it on my latest flame-kk build.

Comment 10

Actual results: During playing, tap the "..." icon, select "Delete" then tap "Cancel" and tap Start icon. The playing graphics is smooth.
