  • My shape layer keeps jumping between its pre-expression and post-expression posi

    Attached is a video of my problem.

    I have an expression on the x and y positions that simply links to a slider that allows me to easily move the shape layer diagonally across the canvas.

    The bottom right position is the desired result, ie what the layer’s position is supposed to be if my expression is turned on, meanwhile the top left position is what the layer’s position would be if I hadn’t added the expression.

    I know I can find an easy workaround, but seriously what the heck is going on? Similar “flickering” glitches have been happening to other layers in other comps as well

    (Tried clearing cache multiple times, restarting, etc. The comp is literally just this shape layer, so there shouldn’t be any weird frame rate problems.)

    Here is my expression for those curious:

    on x position:

    transform.xPosition – effect(“iso z ctrl”)(“Slider”)

    on y position:

    transform.yPosition – effect(“iso z ctrl”)(“Slider”) * effect(“slope”)(“Slider”)
