[kwin] [Bug 359188] kwin_x11 crashes if Minecraft 1.6.4 (Modded) starts and finishing loading

I think yes, because I had a similar bug a long time ago with Plasma where Kwin
mostly crashing everytime, I adding/removing/activating/deactivating a monitor.

Currently I have two Monitors:
DVI (BenQ): Primary Monitor [1920x1080]
VGA (Samsung TFT): Secondary Monitor [1024x768]
HDMI (Samung SmartTV): Gaming Monitor (uses when play Steam-Games with
Controller) [1920x1080; Mirror of BenQ]

Screenshot of KDE's Monitor-Settings: http://i.epvpimg.com/pkvcd.png

Everytime I starting my SmartTV (if not at current boot), kwin crashes.

My Laptop which I using in School and which is running ArchLinux with latest
Updates, crashes often when I unplug a Monitor. But then kwin restarts and
shows me a Crash-Dialog.

It seems that kwin has mayor problems with multiple Monitors or screen
resolutions.

I think that it isn't a fault of my Nvidia GTX 750 Ti because my Laptop only
has a Intel i3 with HD Graphics 2000 which should work fine on Linux.

I found out that if kwin_x11 crashes (shattered screen) I can use the Hotkey to
disable/enable the compositor twice instead of restarting kwin_x11.
Then this image is restored.

This means that it definitly is a bug of the compositor.
Maybe a fullscreen or OpenGL problem?

I tried it.
"$ xev -root -event randr" did not gave me any output while crashing.

Blocking the Compositor with SHIFT + ALT + F12 seems to work best.
As I tried it with the Window-Rule and start Minecraft the Compositor got
blocked but then my middle panel (Windowlist) freezed and kwin shuts down
(windowdecoration was gone).
After I restarted both (kwin_x11 and plasmashell) I noticed that the Hotkey ALT
+ F2 to enter commands did not work (sure only till the next reboot) but my
Hotkey to pop up my Application-Launcher (SUPER + Y).

To sum it up:
- Not a cause of the "Root-Window" ("$ xev -root -event randr" with no output)
- Disabling Compositor works but caused a big crash as I set it as windowrule.

[kwin] [Bug 359188] New: kwin_x11 crashes if Minecraft 1.6.4 (Modded) starts and finishing loading

[Linus via KDE Bugzilla]

https://bugs.kde.org/show_bug.cgi?id=359188

Bug ID: 359188
   Summary: kwin_x11 crashes if Minecraft 1.6.4 (Modded) starts
and finishing loading
   Product: kwin
   Version: 5.4.2
  Platform: Ubuntu Packages
   URL: https://youtu.be/jHEEnC79HZc
OS: Linux
Status: UNCONFIRMED
  Severity: crash
  Priority: NOR
 Component: decorations
  Assignee: kwin-bugs-n...@kde.org
  Reporter: wendefelix1...@gmail.com

Happens if Minecraft 1.6.4 ('Attack of the B-Team') starts.

Reproducible: Sometimes

Steps to Reproduce:
1. Download and start the "Technic Launcher" from http://www.technicpack.net/
(Note: a premium minecraftaccount from minecraft.net is needed to play this)
2. Install the Modpack "Attack of the B-Team"
3. Play it

Actual Results:  
with a 80% chance, kwin_x11 crashes with result as a shattered screen, till it
gets restarted with "$ kwin_x11 --replace"

Expected Results:  
No crash of kwin_x11

I regonized that Minecraft with the current modpack starts in fullscreen and if
loaded wants to exit the fullscreen, I tried it with a Window-Rule that deny
fullscreen. It works but kwin_x11 is still crashing.

I using Kubuntu 15.10 (no alternate PPA/Repo for KDE)
I using a Nvidia GTX 750 Ti with the Nvidia binary driver 352.22

(The freeze in the video is a another bug related to my Nvidia-Card after
boot.)

I don't know weather that is related to this crash, but in case of a V-Sync
failure I added following entrys to the file ~/.profile:
export __GL_YIELD="USLEEP"
export __GL_THREADED_OPTIMIZATIONS=1
This forces all applications to use V-Sync.
