Problems with Display since 10.10.4 update

[aide199]

HI Guys,

I have a 27 inch, late 2013 iMac which currently has Yosemite 10.10.4 installed on it..........but I've ran into some problems since updating to 10.10.4

The problem I have is that if I leave a program windows open or a Safari window open for a long time without closing it, the image of the app or web page seems to 'burn' into my background image and is also shown on the log on page. I then have to re-boot my machine at least 3 or 4 times before the 'burn' disappears.

The problem has only occurred since upgrading to 10.10.4

Is there a way to uninstall 10.10.4 and then try the upgrade again? or can anyone suggest a fix for this issue?

Thanks in advance

That won't be related to the updated. Nor is it being fixed by the restarts, it is fixed just by allowing some time to go by with the screen showing a different or varying image. This is why "screensavers" are called just that...
