Some edges of raster switch to a value of 0 when clipped and pixelpixels are shifted on QGIS

I am trying to clip trees out of a raster layer using polygon I've traced around them. I've created one polygon that I've copied for each tree so that each clipped raster contains the same width and height in pixels. But for some reason, some pixels from the edge become 0 values after the clip, and the pixel will have shifted. I'm guessing it is because my mask layer doesn't cover some pixels completely around the edges. There is no way to clipsnap a polygon to edges of rastersraster pixels that I know of. So how could I avoid this issue.
