Render glitch when using Echo effect

Hi! I'm rendering out a short looping animation in After Effects that uses the Echo effect, and I keep getting digital glitching in the last two seconds of the video (https://vimeo.com/231767989/ebec0aaae7). The video is made up of three pieces of animation drawn in Photoshop, each about 25 frames. The glitching looks like large blocks of horizontal lines that flash in and out. Any ideas how I might be able to fix this? Thanks!

    Try to change the duration of your comp adding a couple of seconds. One of

    the problems with the echo effect is that is looking for frames around the current position of every frame to generate the effect. I'm sure you will solve your problems doing this. It has no sense that this problem occurs in the latest frames of your movie

    I would check a couple of things:

    1.- Try to empty your cache. Go to Edit > Purge > All memory and Disk Cache

    2.- Go to File > Project Settings and under Video Rendering and Effects try to choose another option. Probably you have selected Mercury GPU Acceleration (CUDA/OpenCL). Choose Mercury Software only.

    Once you check these 2 things, try to RAM preview your animation and check what happens.

    1- Yeah, my first instinct was to empty the cache. That's worked for me with issues like this in the past, but didn't work this time.

    2- My Video Rendering and Effects settings were set to Mercury Software only. I tried switching to both of the other settings: Mercury GPU Acceleration (Metal) and Mercury GPU Acceleration (Open CL). They both showed improvements in the RAM preview, but when I rendered it out the same issue appeard.
