Markdown Preview Flickering While Searching

[romerosms]

Current behavior

The headlines and code boxes in the Preview section are currently flickering when you are trying to search for something and a Preview window is being shown (a markdown file is selected). Every single letter you type in the search box causes flicker for those areas. This happens both with headlines (markdown starting with #) and with code boxes. I managed to disable this for headlines by changing the Preview Font Family to Monaco, Consolas but this is annoying and I believe it is safe to say that it needs to be addressed for the benefit of all users. Thanks a lot.

Expected behavior

Steps to reproduce

1. Click on a markdown.
2. Make sure preview window is visible.
3. Type letters in the search box on the left.
