texture problem

hey,
I get this weird texture on all objects I add


please help me to solve this problem!

your GPU seems quite old? (as it shows ), that could cause some issues…

also try if disabling all the baking helps, from Window / Lightning - tab
and clear existing bakes from this dropdown

if you try some older unity version, do you have any problems?
like 5.6 or so… Download Archive

Or different shader for those objects.
