The development of graphics cards for PCs over the last 20 years has been tremendous.
The marketing window of a new card is very short, often only about 6 months. As a result I suspect the graphics card driver shipped with the card can often be a rushed job and is often buggy. The card manufacturer hopes to fix the bugs before you start using it in anger and you will have updated it. The update does not always happen, resulting in you having a system with buggy graphics.
The major problem with buggy graphics card drivers is that programs may appear to behave ‘strangely’, leaving both you and the software developer frustrated.
The solution is often easy; download the latest driver. Search the web and it is highly likely that you will find a newer version than the one you are using. Then, hopefully, the problem will disappear.
