@Turgon-Aran-Gondolin thanks for reporting! I also noticed the bug when previewing long-to-compile tex files

[Turgon-Aran-Gondolin]

Thanks for replying! I also found that sometimes the bug appears when I enter the insert mode in vim. The pdf file goes dark when I'm in insert mode and reappear for 1s after I exit it and go dark again, which is briefer this time and after 1 or 2s everything is back to normal.

[badouralix]

Hmm, going dark is weird... Which pdf viewer are you using?

How about setting update time a bit higher?
