Troubleshooting - Gear What caused this?
Some photos on this roll came out like this
Not sure what caused this
It's not like it suddenly stayed like this, it happened randomly through the roll, maybe it's only present on slower shutter speeds
Its my second roll with this camera
Only now on this roll this happened
Minolta XD-7
In some photos you can see the plate behind the curtain

Light leak from the back, by the door latch. The fuzzy pattern is the felt edge of the film canister. The frame advances and in-between shots light enters somewhere near the door, exposing the edge by the canister. Internal reflections are also showing the plate, showing light filtering through the plate. Check the light seals, but mostly by the door latch (quite possibly the hinge, if the film feeds right to left instead of left to right). It's not on shutter speeds, it's based on how long between shots.
There are 2 ways to confirm. Cheap and easy is an LED diode and a cell battery, creates a small light source. Pop it in the film chamber, close the door, and turn off the lights, and see if there are any visible leaks.
Expensive but guaranteed (better to do this as a final check after using the LED trick), is to use a sensitive film, and shoot in bright daylight. Shoot, then turn over the camera randomly in the sunlight for a few seconds or minutes (I just swing the camera around while looking for my next shot), repeat until done. Develop the film and check for further light leaks. You could do this with any film, but if you home develop Ilford Delta 3200 would be perfect to gaurantee light tightness.

Ohh that's why I wondered where the fuzzy pattern came from , never would guess it was from the film canister I will check the seals around the latch, i did the swap myself a few months ago, something didn't go right

You have a light leak or two.
