Cursor is transparent

[slavoutich]

After the recent changes to cursor rendering (commit 2dc10aa, I guess), cursor is transparent, which makes GUI completely unusable. Visually a symbol under cursor is blinking in normal mode and part of it (covered by vertical line cursor) is blinking in input mode.

(Linux x86-64, latest master version)

Maybe this is related to #96. Can you try to run with env NVIM_GTK_DOUBLE_BUFFER=1 ?

[slavoutich]

I do precisely that. Without it i successfully reproduce #96. (Setting NVIM_GTK_DOUBLE_BUFFER=0 does not help the cursor, though.)

Looks like need to revert this changes and rewrite them.
Can you provide screen shot or video with problem?

[slavoutich]

Screencast is here.

Confirm now, everything works. I guess that the issue may be closed. (Not only "default" colorscheme was affected, I just made an empty configuration to make sure that issue is not due to my init.vim.)

The bug resurfaced on Fedora 31. NVIM_GTK_DOUBLE_BUFFER doesn't help.
Any ideas?
