Tip up canopy was my greatest challenge . . .
The finished canopy and frame is decidedly flexible and it is easy to twist the back if not lifted from the center. I am not flying but have completed the canopy fitting with about a 1000 openings. Have you tried lifting the corner then opening from the top center and then when closing only using the center latch handle, is it still twisted and scrape on one side?
Does it have plastic guides on the roll bar to guide the last 3" before closing?
Getting deeper. If it IS twisted, now we need to know how much, and if it is a combination of yaw and twist. Then, how is the front skin mating to the fuse? i.e. if simply rolled a bit, the mate with the fuse should also show it being off.
There are many indicators for what is really happening from operating technique to lets call it "assembly tolerance". I have gotten mine to fit pretty well around the perimeter and had to use a lot of off book tricks.
Pictures would be a big help.
Edit - you might remove the gas struts for a check to see if how the canopy acts unstressed.
