STEPS TO REPRODUCE
1. On a computer with an Nvidia 970M, using the (535) proprietary drivers, let
the computer go to sleep / hibernate, (regular sleep mode normally isn't a
problem - it comes right back after pressing the shift key or something, but if
you leave the computer along for longer, eventually it goes into a "deeper
sleep," (/hibernate?) which the computer can often not recover from and needs
to be force-shutdown and rebooted. ~1/10-15 times, the computer will
eventually come back up from this "deeper sleep," (/hibernate - using whatever
is the default power management in Neon Unstable) and that's when this happens
- the rare time that the computer doesn't have to be force-shutdown and
rebooted).
2. Press the shift, (or other) key to resume.
3. Login to X11 session
OBSERVED RESULT
Both of the previously-opened windows - Firefox and "About this System" were
still open and shown, but Firefox just showed colored garble inside the window
itself and the "About this System" window was solid black. When you clicked on
the Firefox window, it immediately recovered from garbled colors to the proper
content in the window before the computer went to sleep. Unfortunately, even
after clicking multiple times in the "About this System" window and trying to
move it around, just in case, it remained solid black, (see attached image
file).
EXPECTED RESULT
Expected the desktop, including the content of any open windows, to look
exactly the same as they did before the system entered (deeper) sleep mode.
