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.
