LM324: how to remove the effect that pulse from output of LM324

Hi there,

I made a comparator with LM324 and its circuit is as below:

I found an issue that when LM324 powers on, at the very beginning, there is a pulse happened at output of the OP. The bandwidth of the pulse is at XX milliseconds. I got some questions as below:

1. Is the pulse caused by the bias of IN-? The parameter of (R86//R90)*C56 determines bandwidth of the pulse?

2. If I reduce the value of R86 and C56, can the pulse become short and even disappears?
