Quick flashing prompt when executing ideavim keymap in Webstorm

Question

When I execute a keymap defined in my .ideavim such as this:

nnoremap <leader>gf :action GotoFile<cr>

the popup flashes quickly and goes away. (This occurs 95% of the time and once in awhile it stays up as expected. I tried many combinations of typing slow/quick and found no pattern that tends to cause it to happen more.)

If I use ctrl+shift+N, it pops up and waits for my input as expected.

Any suggestions on how to debug or fix this so the prompt/popup stays up?

Additional info:

• I am running XFCE4 (Debian-Jessie) and not sure if there is some fight for window focus. My XFCE configuration is pretty vanilla out of the box though. I already played with Window Manager > Focus and Window Manager Tweaks settings too...
• In Webstorm's Settings > Other Settings > Vim Emulation, I set the Handler for most items to vim.

• Webstorm version:

  WebStorm 2016.1.3
  Build #WS-145.1616, built on May 27, 2016
  JRE: 1.8.0_91-b14 amd64
  JVM: Java HotSpot(TM) 64-Bit Server VM by Oracle Corporation
  

• Note: I am not using OpenJDK. (The problem occurs with OpenJDK to, but I switched after reading WebStorm in XFCE/Xmonad – JetBrains Support with the hope it would be fixed. Unfortunately this problem persists for me though.)

Update: I almost resolved the issue by going to Webstorm's Settings > Appearance & Behavior > Appearance and unchecking "Hide navigation popups on focus loss". This prevents the flashing popup. However now the focus isn't on the popup. Any ideas of what is stealing the focus?

This problem is fixed in EAP builds of IdeaVim. Try https://github.com/JetBrains/ideavim#get-an-early-access.
