Description abhigenie92 2017-05-15 17:21:54 UTC

**Issue details:**

Whenever I install nvidia drivers on my issue. 

 1. The icon-only Task manager animations are super fast, not smooth. 
 2. When I boot my PC, CPU usage is 100%! 
 3. When I boot my PC, the kde boot screen flashes several times and loading wheel animation is super fast not smooth.

Reproducibility: It happens always.
**Related Issues:**

It might relate to these, but I am not sure. (Listed in decreasing order of relevance.):

Video showing the issue:
https://vimeo.com/217543616
0:03-0:04- Kde boot screen animation rotating wheel not smooth, too fast.
0:05-0:06- Screen flasjes for no reason.
0:35 - High CPU on CPU 2 usage 92%
0:43 -High CU usage on graph
0:55 onwards icon-manager fast not smooth animation.

I would like to add the 100% CPU usage happens from time to time. That is, even after startup.

Comment 2 Fang He 2017-07-06 10:57:44 UTC

I have the same problem. I am using PRIME with

00:02.0 VGA compatible controller: Intel Corporation HD Graphics 530 (rev 06)
01:00.0 3D controller: NVIDIA Corporation GM206M [GeForce GTX 965M] (rev a1)

After enabling NVIDIA kernel mode setting by adding nvidia-drm.modeset=1 to kernel parameter, the problem is solved.

Some information:
OS: Arch Linux
Kernel: x86_64 Linux 4.11.9-1-ARCH
DE: KDE 5.35.0 / Plasma 5.10.3
CPU: Intel Core i7-6700HQ
GPU: GeForce GTX 965M

Comment 3 David Edmundson 2017-07-06 11:50:04 UTC

Can both of you list your Qt versions please.

Comment 4 David Edmundson 2017-07-06 21:37:02 UTC

Please reset the status to unconfirmed when you reply.

Comment 5 Fang He 2017-07-07 01:30:03 UTC

Qt: 5.9.1
nvidia: 381.22
xf86-video-intel: 1:2.99.917+777+g6babcf15

Comment 6 Fang He 2017-07-07 01:33:30 UTC

Seems that I do not have privileges change the status.

Comment 7 Christoph Feck 2017-07-17 16:09:05 UTC

Thanks for the update; changing status.

Comment 8 David Edmundson 2017-07-19 09:56:37 UTC

Can you try closing plasmashell (kquitapp5 plasmashell) and reporting on both the following:

QSG_FIXED_ANIMATION_STEP=yes plasmashell 

QT_QUICK_BACKEND=software plasmashell

Comment 9 Fang He 2017-07-21 14:00:15 UTC

Sorry that I switched to Intel graphics card due to hot summer, and I switched to i3wm as well. I can not test your solutions right now.

Comment 10 David Edmundson 2017-07-30 22:52:18 UTC

Then we can't continue debugging this. Closing.
