Hi! I have downloaded and installed SolidWorks but the scene is not working well and I cannot see always what I am designing. The scene I see is a black background with white dots (attached image) and I have tried to change it but I cannot. If I change it to blue, for example, the white dots become blue but the background is still black. In addtion to this, the dots keep moving so it is really disturbing and impossible to work. I have tried to uninstall it and installing it again but the same thing happens, with both the 2021 and 2020 versions. I have been looking on the Internet and I have found nothing. I have checked the computer's requirements and my computer meets all of them. How can I solve this problem?
