El Cap / Parallells graphics issue in Beta 3

Since this morning I am having graphics issues in Parallels with El Cap Beta 3 and it makes Parallels unusable. Anybody has an idea what that could be and how to fix it? Anybody else seeing this issue?

Thanks guys

 

Hi @PascalT, could you please provide us with the steps-by-steps instructions in order to reproduce the issue on our side.

 

So basically I downloaded the latest public Beta of El Capitan yesterday night.

Then this morning I started Parallels to run my Bloomberg application but the moment I start Windows 7 it starts to flicker in strong purple/pink and I have full functionality but cannot really see much on the screen. I just tried to do a screencast and take some screenshots but somehow when I try to do this the problem doesn't show in the same way.

Something to add is that I think it seems to be related to movement from other the screen or the mouse that causes these sharp purples to appear.

 

Here is a little video of the problem. Anybody can help me?

So it seems that this issue is only affecting my 5k iMac Retina. I have just installed the same Beta of el Cap on my Macbook Pro Retina and it works flawless. Any suggestions somebody?

 

It almost looks like the desktop is using EGA Color. MInd checking the graphic adapter in Windows?

 

I actually figured it out. It's an El Cap issue that only happens on 5k iMacs so I assume that Apple will fix this on the next update. Some of my friends that have the same Mac see the issue with their Screensavers.
