Texture showing artifacts like colored pixels

My textures is showing up like this. It says “ video memory has been exhausted” but i have other projects with this memory error as well but never got these texture artifacts until now.

Any help clearing what this is caused by is greatly appreciated. Is it simply because my graphics card is out of memory to show the textures fully?

Did you manage to fix it? I have the same problem. 5.1.1
