描述

Seems that the bug from https://github.com/MacDownApp/macdown/issues/253 has come back in the latest build from master.

I get nasty flickering from the preview pane any time I type a keystroke.

Here's a demo video.

This is on a build of master as of today (March 13, 2019) on Mojave 10.14.3

研究方向
Investigate the preview pane update logic in the MacDown codebase. Look for recent changes that could cause double rendering or event conflicts. Review the fix from issue #253 to understand the original problem. Test typing at various speeds to reproduce the flickering and identify the root cause.
