I'm running the bed that came with my Ender 3 pro (using a pei sheet, this is repeatable with glass too), been having this issue for a while I think. Is it time to replace the bed?
Update: Figured it out, what my bl touch was attached to was very loose, and was going up on the far side of the x gantry. and it's now fine.
Put something flat on your bed. It should have a noticeable gap between the bed and the piece
Or you have something wrong with the level sensor
I agree it seems really odd how consistent the warpage is along the back edge. Is there a sticker or something on the bed there that the level sensor is hitting?
There's not these are pretty broken in sheets that I've had for a while
You said it's the same without the sheet, just directly on the glass? If so, I'd definitely consider swapping it, though check it first with a straight edge like the other person suggested. Just stick a flashlight behind it and look for light to come through. Really odd warpage though.
My Artillery Sidewinder glass bed was also warped but it looked like a bowl shape not like a Fast and Furious car with a giant spoiler.
