Possibly the GPU card is either overheating or is going bad or is Overclocked.  True sometimes drivers may cause artifacts but since it is occurring even while on the desktop or all the time it may not be the driver.

Stress test your GPU card and see what happens. If it passes or fails. You can check temperatures and voltages, etc while the test is running.

Is this, by an chance, bought second hand or used?

I have no idea on how to repair GPU cards. Some Users have "Baked" the card according to the Internet. But some professionals techs don't agree with the method.

Try stress testing and see what happens.

Otherwise, contact the person you bought it from and see what he recommends.

I have lots of experience with repairing video cards

the fuzzy donut can find a sick card fast

What is the "fuzzy Donut"?

Would "Baking" the GPU card help in this case even though colesdav doesn't recommend this type of repairs?

Dont bake the card in an oven and definitely do not use an oven that you use for cooking food.
There are very dangerous chemicals used on printed circuit boards that will contaminate an oven.

I have fixed a number of GPUs using a home made DIY method described here:

However I recommend using a proper reflow station - best place to try is ask a local University or Technical College if they will use your GPU to test their reflow station for a small fee.

Good Luck.
