[bug] Words cannot be displayed in Vim in some cases

[Naccl]

Describe the bug

In maximize window or full screen, when I move the cursor to the front of a word(perhaps a code segment), then quit vim and re-enter vim, sometimes this word will not be displayed until I modify it.
It doesn't seem to happen in smaller window.

Debugging with xterm.js is not easy in both cases you’ve report. I’ll keep up with you if I find any solution.
