Description Ghost 2017-06-29 18:22:25 UTC 
What happens:

Creating a new document in Krita causes Kwin to crash and generate the following output in dmesg: "NVRM: Xid (PCI:0000:01:00): 31, Ch 00000020, engmask 00000101, intr 10000000"

Steps to reproduce:

1)Ensure that OpenGL is set as rendering backend in Kwin compositing configuration;
2)Open Krita and enable OpenGL in display settings tab;
3)Create a new file;

Steps to prevent that to occur:

-Suspending compositing in Kwin;

-Changing rendering backend to XRender;

-Disabling OpenGL in Krita.

(Once a new file was created and the following preventives was taken, you may re-enable OpenGL in both Krita and Kwin compositing, and freely create new files.)

Additional information:

The bug occurs upon updating to the version 3.1.4-2.
Unfortunately, I'm not able to run the previous version of Krita due to missing shared libraries error: "krita: error while loading shared libraries: libgsl.so.19: cannot open shared object file: No such file or directory"

Although, I can't deny or confirm that the bug may be related to the update of the core packages of Plasma Desktop [kwin (5.10.2-2 -> 5.10.3-1) etc.], there's no problem running other OpenGL applications.

I'm using the newest and stable NVIDIA proprietary driver: version 381.22-3.

Please report the kwin crash separately, even if you believe the issue is with krita.

Hi Kamil,

I'm afraid that this is so specific to your archlinux setup that we cannot do anything with your report. Sorry...

Hi Boudewijn,

The problem I had described here turned out to be the issue with the proprietary Nvidia driver + Kwin combo.

At the moment I don't use KDE Plasma, yet I can confirm that Krita works flawlessly on my system.

Good to hear!
