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.

Took me a moment to realize this wasn’t a figure of your bed that you sleep in
This is a mechanical issue with your motion system, not your bed. If it were the bed the probably would not be consistent between different bed surfaces.
I would make sure the roller paths are clear and flat the entire length of the path. More than likely that is the cause. Also check that the cables are sufficiently long so they aren’t putting excess tension on the tool head or bed at the extents of travel.
I had a roller lifting up at the edge of the bed that caused this. In my case is defined the bed mesh to large in klipper and the hot end was pushing up metal slope on thex gantry.
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.
I just put a metal ruler across it, and there’s a noticeable gap
This to me looks like it’s time to buy a new bed, stick with Creality or is there a better brand to upgrade to?
I’d get a good tempered glass sheet, creality sells good ones cheap. it’ll go right on top of this. You might use a bit of thermal paste to seal those gaps and make sure it heats evenly. One side of the glass will be textured, I prefer the smooth side.
Make sure there isn’t too much tension on the cables to the hotend assembly. Could be pulling too tight and lifting a bit when it gets too the far side
This is the right answer. You’re hot end is pulling tight and causing this skew.
IDK, that’s weirdly consistent
I got a glass bed then and simply put’ it on the stock bed. Takes 5 degrees more heat and a little longer to heat up but I am very happy with it. Btw, when you are at it: I would isolate the bottom side of the bed to conserve energy. You can buy ready made isolations with a glue- and an aluminium side.
