Unintended glitches of black or white vertical lines are layered on the image rendering result.

Unintended glitches are layered on top of the production in PNG and Jpeg.
I tried checking for hardware acceleration, etc. and it made no difference.
What is the cause of this?
PDF outputs fine.
I ended up outputting in PDF and rendering through Photoshop.
These issues do not occur with Adobe products.

Hi @K.Shiba and welcome to the forums,

This is typically a result of having Hardware Acceleration enabled in Affinity Designer...

Just to clarify, In Affinity Designer,  if you go to Edit → Settings and then select Performance from the list on the Left, is Hardware Acceleration unchecked? If not, uncheck it which will require you to reboot Designer, re-open your file and re-export it to see if it fixes the issue.

If Hardware Acceleration is already unchecked, ensure your NVIDIA and AMD drivers are completely up to date.

Let us know if either option fixes the issue...

If not can you upload a sample file so we can make sure there are no issues with the file itself?
