[#1]

These lines always appear after I pre compose some layers and it only appear on one frame

This issue start from a year ago and I can't find a way to fix this.... Please help! Thank you!!

PS: These lines are sticking to the pre composed layer, if I hide the  pre composed layer, these line will dissappear as well.

Start by checking your system's graphics driver. Update it and also verify AE's hardware acceleration settings. Anything beyond that will require more specific info liek actual system info, details about effects used, specs of the source files and so on.
