Troubleshooting
1. Effect of gruvbox_256palette.sh gets reset on Alt-Tab
That's known issue with Ubuntu GTK-themes and//or VTE-based terminals. Refer † for more details. Known affected terms are Gnome Terminal, Terminator and Lilyterm and probably more VTE-based. Though, with Lilyterm option 'Dim text when inactive' set off, everything works fine. There is no known solution//workaround to fix this. If you're disappointed with such behavior, please report issues to terminal developers, there no thing I can currently do with that.
2. Cannot set contrast
If you are setting the value of g:gruvbox_contrast_dark
or g:gruvbox_contrast_light
and do not see any change try
setting the contrast before colorscheme gruvbox
in your configuration.
