Window sometimes goes dark after waking from suspend
I have Gnome Terminal windows open for long times (sometimes days). Sometimes I will come to my computer, and the Gnome Terminal window will be dark. This happens very intermittently but it always seems to be just after waking and unlocking my computer. Even the window decorations are darker. The only workaround I know is to restart my terminal.
In the screenshot you can see the terminal on the right is much darker than the one on the left (which I just opened).
