Description:
I experience a weird problem on my desktop system. And it seems to be graphics vendor dependend. Steps to reproduce: Use a NVIDIA graphics card (Tested with Geforce 9600GT and Geforce GT520) Use either nvidia or nouveau (No difference) Start a youtube video and move the mouse fast in circles over the video. The video begins to stutter and the CPU load rises up to 100%. If I try the same on my laptop (Intel graphics) the problem doesn't appear. If I try this with Mozilla's 64bit builds of Firefox 24.0 the problem doesn't appear, too. |
This task depends upon

I tried to compile firefox on my desktop system. But it crashes while linking.
Without PGO compilation works. And at the moment my problem seems to be fixed.
But that needs further testing.
As this happens infrequent i just thought Mozilla builds are fine.
Now I tried the desktop Harddrive in another AMD system (Sempron 2700+ and Geforce 630GT).
There's everything alright.
Could that be a rare production fault? Which part of my hardware is broken?
Already tested the graphics card in the Sempron system. That one is OK.
RAM, CPU, mainboard?
Further investigation shows, that this problem also effects the two systems which do not show the video problems
I think the video slowdowns are a sideeffect of the high CPU usage.
Moving my mouse very fast produces a CPU load of 40-60%
