How thick is the Trex?
If the bottom is skewed from the top, then you're likely still on an angle at the top but dragging the blade through the material against the angle. If going slower doesn't help, then angle is the problem.
A blade's natural path is dependent on the "set" of the teeth. Rare is the blade that is "set" perfectly straight from the factory; most blades require that the saw be held on a bit of a bias one way or the other to cut a truly perfect path. We used to hand-set the teeth of all factory-new blades with a drift and hammer prior to sharpening with a hand-file (lasers replaced our old jigsaws long ago).
A thicker blade may help, but would only correct for what I think is a a technique and "set" problem. Jigsaws do take considerable experience to operate well.
This is honestly the most absurd post I've ever read about anything to do with carpentry.
Op. you must be referring to the blade not cutting straight as in up and down,so the cut is curved in respect to the top of the lumber to the bottom.
First off what kind of jigsaw and does it have a switch to adjust the blades travel.as in the blade cutting a level stroke or a rounded stroke. Either or you are simply pushing too hard. Try holding the jigsaw back,and letting the blades stroke do the cutting.
As far as the comment above I've built easily a couple million sq/ft of residential and easily 1/2 million sq/ft decks,and I cannot even fathom trying to make sense of that comment.
3:39 am, and this is what's presented. Baffling
