Hi, I'm running into a problem I have never seen before.

I'm making a render with neon tubes. so there are 2 glass tubes wrapped around a blackbody emission tube. However for some reason the pixel-edges along alot of tubes are very slightly jagged.

Along the red line you can see it the most.

This is on 100% view, so I'm not zooming in. Increasing samples doesn't really seem to help and increasing resolution doesn't help either.

I'm not sure what you mean, can you do a render where the problem is a little more obvious?

Hi Tehchriis,
it seems that there is too much contrast and you see the jaggling effect. You can reduce the emission, increase the Highlight brightness compression in Camera Imager, and slightly increase the Filter value in the Kernel settings. Increasing this value acts like increasing the antialiasing in other render, but blurs all the image, so use it carefully.

P.S. if you can upload as attachment your screenshots instead of using external links, it would be much better for us, thanks.

I recall having a slight jaggedness around a screen i made. This screen had a piece of geometry for glass and another piece of geometry for the screen which had the emission material on it. I got rid of the jaggedness by moving them a little further apart. They weren't touching to begin with but by moving them apart just a little more, solve the issue.
