So, I've been attempting to render my video now at 4K 60FPS. The video completely renders, but there is a strange visual glitch when all visual elements besides the text and main background fade in where they appear to be blinking in and out of view before going really cursed looking for a moment (see the screenshots), before finally settling and being fine for the rest of the video.

At points when these elements fade out, there are no problems. When they fade back in, no problems. When new elements are introduced and fade in, there are still no problems. It's just the first time they show up in the video.

How is how it looks before it settles, after the blinking:

Here is how it should look:

Here are my render settings:

Here is where it happens on the timeline:

Now, none of this happens on the video preview and it doesn't affect me when rendering at 720p or 1080p, just 4K.

I've done very similar to this countless times but this one is breaking for some reason.

I've already tried a few quick fixes from Google like turning down that max memory setting to 0mb and trying to render at different resolutions. The 0mb fix took about 5 hours and still had the glitch, and as I've already said, lower resolutions work fine.

The media in question is quite big, the music score you see is a massive extremely long PNG, but to be clear, it is actually significantly shorter than the length I usually work with. It is 600DPI which is also what I usually work with. Usually takes an age to render but it works fine.

What is confusing me is why it looks fine on the render preview but has the issue when I watch the final export.

Also, some extra info: In terms of FX, I am using a glow on the bright green arrows as per the screen shot, this is not animated. I am also using the invert effect on the score as it is black by default.
