After yanking a text from Vim I cannot paste the clipboard content into Idea's editor window. I can, however, paste it in every other window (browser, terminal etc.).
The text becomes "pastable" (strangely) after I run command in a terminal:
xclip -sel c -o | xclip -sel c
or paste a line somewhere and copy it manually (Ctrl-C or mouse).
I have set options
set clipboard+=unnamed, unnamedplus
in both Idea (ideavim) and vim.
My system is Fedora 25. This problem manifested itself after I changed distribution, so maybe Wayland has something to do with it.
Just want to share my situation. I've installed both xclip and xsel for neovim. It turns out that the contents piped to xsel was not recognized by intellij.
I uninstalled xsel and it works fine.
