Random screen blackouts Qubes 3.1

[FWM]

So a problem im having is randomly it looks like the screen saver will try come on, even though im typing or using the mouse.

And even if i move the mouse the screen will stay black, and i have to move mouse to the tool bar and click open windows, which will remove the blackness only over that window.

Seems very much like some kind of graphic bug.

But its also the typo of glitchy thing that ive seen when computers/GPUs get hot.

Is this a know issue?
Is there a tool i can use to monitor my system temps? where should i install such tool? in dom0?

Thanks

PS: Let me know if there is a log file somewhere i could post to help diagnose whats going on.
