Random white and red blocks across the screen when selecting data

[EmmaE1]

Hi,

Since I've updated to the latest version, I've been getting odd blocks (mainly red and white squares) on my map when selecting data on my map. If I don't have anything selected the blocks dissapear. The position, size, and colour of the blocks change depending on my zoom level (see photos below). Is this an issue with my graphics card or symbology settings?

Thanks!
