Well,  I play some games and suddenly from time to time this issue randomly appears:

What can be causing this? And is there a way to make it not happen again. 

This is a 1994 model with SW1.1

Is it intermittent on the same game, or is it with some games and not others?

There are generally two kinds of image problems like this on tube TV sets, burn in and edge "ringing." Burn in is caused by displaying a non moving image for a long time so that it "burns in" into the phosphors. Ringing is usually caused by transitions from edges usually of different brightness and can be made much worse if the TVs "sharpness" is turned up too high. In fact, most calibrators in the day were adamant that the sharpness control be turned way down as it caused notable edge ringing artifacts such as you're seeing.

Try turning sharpness down and maybe play with brightness and contrast if the sharpness control doesn't completely solve it.

I'm afraid I'm recovering from the BeoVirus. Sad

If you call up the menu of the TV when this problem is on, do you see the same ghosting next to the OSD displays? If yes, it’s internal to the TV set. My MX6000 does that as well, usually while warming up. I suspect it is a bad solder somewhere but haven’t bothered investigating further as I rarely use the set, and the problem eventually goes away every time.

If the TVs own menu is fine,  check the cable.
Insufficient shielding (too long cable etc.) can cause these "echoes".

Every game, until it goes away. But sometimes it comes back. 

 

Will check the menus.

But there is also a constant issue, in the first world of super Mario world there is a level with spinning platforms. There is constant ghosting in front of thees platforms. 

 

Will check the menus.

I can now confirm I have this issue in tv menus as well.

Is there something that can be done about this in the service menu or is the tv beyond saving?
