Description

Something that bothers me is how Glide64 output pixels when you enable High Internal Resolution. It distorts the pixels, throwing random pixels sizes at random positions.

On the other hand, gnl64 output these pixels correctly. Too bad it isn't so compatible as Glide64.

The issue can be seen in these screnshots and comparison:

Research direction

Reproduce the distortion with Glide64 while High Internal Resolution is enabled, using the linked screenshots and comparison as the visual reference. Compare the rendered pixels with gnl64 output; done means Glide64 no longer produces randomly sized or positioned pixels in the affected graphics.
