Description Ilyas B Arinov 2022-01-05 22:34:44 UTC 
SUMMARY
***
Comparing big files with small files makes GUI unusable. Optimize for large files enabled.
***


STEPS TO REPRODUCE
1. Open any react package.json (~1MB) as A.
2. Open any small file as B.
3. Enjoy.

OBSERVED RESULT
GUI became unresponsive and extremely slow. I guess because of curved lines rendering.

EXPECTED RESULT
Fast and responsive GUI no matter how huge text file was opened.
