Very strange corners

Hello, everybody. I have a somewhat annoying problem that I am struggling to solve. Here is my print with PETG, and as you can see, the overall print is fine except for the corners. For some reason, they look like this. Does anybody have any ideas why? I would appreciate any help. Thank you!

Forgot to mention printing speed is 150, Acc. is 7k, Corner Velocity 5 Ok, i have finally figure it out. It was pressure advance. After finding the correct one for my speeds all corners prints normally.

That looking gaps on corners most of the time indeed the sign of incorrect pressure advance
