描述

macOS version: 12.1 (Monterey) Kap version: 3.5.1

Steps to reproduce

  • Record a screencast
  • Convert to Gif (tested at many different settings, even original size)

Current behaviour

Here is the current behaviour when exporting as a gif (note the dot matrix pattern, possibly a compression artefact?)

Bad Artefacts

Unfortunately even at original resolution, I can still see it, but obviously it's fainter.

研究方向
The bug involves dot matrix artifacts when exporting GIFs. Investigate the GIF encoding pipeline in Kap, likely using a library like gifencoder or similar. Look at the export configuration settings for dithering and quantization. Check if there are any open discussions or attempted fixes in the comments. Consider implementing a fix by adjusting the encoder parameters or switching to a different library.
