            Bug ID: 92504
           Summary: [NVA5] Corruption in Plasma 5 on resume after changing
                    screen configuration
           Product: Mesa
           Version: git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW

dmesg output (since boot)

Steps to reproduce:
 * Use laptop with "NVIDIA Corporation GT216M [GeForce GT 330M]" or similar
 * Install KDE Plasma 5
 * Reboot
 * Log in to Plasma 5 desktop

 * Open the main menu and do *Quit* -> *Suspend*
 * Wait for the system to suspend
 * Resume the system and unlock the screen
 * Disconnect or connect external monitor (use *Menu* -> *Computer* -> *System
settings* -> *Screen* to force screen detection if it doesn't happen
automatically)

 * Open the main menu and do *Quit* -> *Suspend*
 * Wait for the system to suspend
 * Resume the system and unlock the screen
 * Open the main menu, network indicator or any other menu from the panel
(`plasmashell`)

*What should happen?*

Nothing - it should "just work"

*What happens instead?*

Massive corruption the first time you open any menu

Also, after reproducing this error a few times without rebooting, the
corruption becomes worse on every suspend until the system hangs. I'm not sure
if this is related through…

*Where was this error produced?*

Tanglu Linux 4.0 ALPHA (Debian based) using:
 * Latest 4.2.0-trunk linux-image
 * MESA git snapshot or MESA 11.0.2
 * LibDRM 2.4.64
 * X11 1.17.2
 * xorg-video-nouveau 1.0.11
