Dropping half FPS while moving mouse
Hi all,
After upgrading the system, I found that 3D game is not working properly.
When I move the mouse, the game's FPS will drop by half.
When the mouse is stationary, or click and hold the screen within the game, the FPS will return to normal, no matter how I moved.
I try to disable vsync, but it is no effect.
The problem is exist in both discrete graphics and integrated graphics.
Mouse is stationary or outside the window
Moving mouse
Anyone know where is the problem?
System:
Intel(R) Core(TM) i7-4710HQ
NVIDIA GeForce GTX 850M
Linux 4.0.1-1-ARCH
Nvidia 349.16-2
xf86-video-intel 2.99.917-5
xorg-server 1.17.1-5
wine 1.7.41-1

Sorry, I restored the content.
I think this is a kernel bug, I downgrade to linux-3.19.3-3, then it returned to normal.
But I don't know how to report it.
It related to 3 large projects (linux, mesa, wine), but I did not find where is the problem.

Thank you 
I don't have an answer (maybe it has something to do with interrupts) but if downgrading the kernel helped then you could be right.

Re: Dropping half FPS while moving mouse
I had similar performance issues with flash videos and problem was too high mouse polling rate, https://wiki.archlinux.org/index.php/Mouse_polling_rate
By default it was polling at 1000 hz and videos would start to lag everytime I moved mouse, but it stopped when I lowered rate to 250hz.

Re: Dropping half FPS while moving mouse
If a kernel downgrade helps, did you compare the kernel configurations (zcat /proc/config.gz) or consider a git bisect of the kernel?
