So the problem is in my textures in the perspective viewport, actually not in the textures but in the fact that they are not seen on the viewport. What I only see is the frame of an object or I can see the mesh when i hit f4, but I just can't see the object at all. Colors of all objects I create interflow with the gray basic background.
Maybe there is some way to fix this?
Thank you in an advance!
Check your material settings, maybe a problem with opacity.
Check the objects properties and make sure See-Through is not selected.
I have seen this before when there were iussues with the display driver/card as Steve_Curley mentions.
To test the it go to Customize-Preferences and click on Viewports tab - Choose Driver
Choose one of the others, try the Legacy drivers, and see if it makes a difference.
