[solved] Laggy xorg (input+display) with high cpu usage

Hi everybody, i got a problem since todays reboot.

While rendering a Video with openshot (Settings: MP4 (h.264), HD 1080p 60FPS, High), my mouse gets all laggy and some of the input gets ignored.
Keyboard input is laggy to, but at least every keystroke is displayed eventually. Before todays reboot, i would not notice any lag what so ever while rendering.
I also noticed, that openshot would take only ~65% cpu (conky) instead of >90%.

EDIT: This behavior can be reproduced with 4-5 instances of:

#!/bin/bash
while : ; do
    true
done

The input gets laggy and deadbeef has issues to play audio...

Hardware: i7 3820, MSI X79A GD45, 16gb Corsair Memory, NVIDIA GeForce 660 Ti

My last reboot was on 15. March.
Since then, i installed/upgraded the following packages:

I can't remember changing anything else.

To find the problem, i tried downgrading various packages, but failed to fix this issue.
First try:

[ALPM] downgraded ffmpeg (1:2.6.1-1 -> 1:2.6-3)

Second try: Downgrade linux + dependencies (nvidia, virtualbox-host-modules)

[2015-03-19 16:17] [ALPM] downgraded linux (3.19.2-1 -> 3.18.6-1)
[2015-03-19 16:18] [ALPM] downgraded nvidia (346.47-10 -> 346.47-3)
[2015-03-19 16:18] [ALPM] downgraded virtualbox-host-modules (4.3.26-3 -> 4.3.24-1)

Afterwards I upgraded them again,then i tried downgrading libvdpau (1.1-1 -> 1.0-1). Well, didn't get rid of my lags.
Edit: Downgrade xorg-server-* did not work.

So, does anybody have a clue, what could have caused this behavior change while rendering?
How can i debug this?

Thanks in advance,
Diraso

EDIT:
I marked this as solved, but i still don't know, what caused this.
- After downgrading packages again did not help, i turned my computer off and removed the current for a few seconds
- Then I booted windows to play a few rounds
- In a pause i played with ClickBiosII from MSI and switched some settings around
- Boot linux -> No more lags with high cpu usage. Upgraded Packages again -> No lags.

I guess the poweroff and a few secs without power did the thing, but i'm not sure.
Feel free to post your theories
