I recently moved into a new house and have noticed that the sliding door frame slightly bends toward the inside of the house.
If you open the door and stand perpendicular to the door in the door opening, the edges of the frame (where the door slides into) look similar to 2 right parenthesis.
Sliding the door in, it kind of gets stuck on the inside bend, but it is easy to push through it
I will share real picture below. The parenthesis just give an exaggerated idea of the shape because it is hard to see in the picture/video.
Is this a structural problem? Is there a way to straighten it out? Can I just leave it as-is?
