System Information
Operating system: Pop!_OS 20.10
Graphics card: RTX 3080, Driver Version: 455.38

Blender Version
Broken: 2.93 (Sergey mentioned this seems to happen from 2.91 on)
Worked: 2.90

The displayed render results shows irregularly spaced horizontal line artifacts, even at 100% zoom level (where the image display should be pixel accurate). These appear to be happening only when displaying an image, the saved image is artifact free. This seems to happen also on externally loaded images.

Render display in current master:

In Blender 2.90

Example file: image_editor_line_drawing_error.blend

This appears to be a duplicate of #82999 (In 2.91.0 Image Editor fractional zoom does not display images correctly with some image resolution and configuration of the working areas.)
As in the other report, I also cannot reproduce the problem.
It may be a problem only with Nvidia GPUs.
