unusual pixel movements

I'm having trouble with sprites, they're all coming up strangely across several projects. they're missing pixels for a moment, then they return as they should be. a persistent issue regarding this the player sprite; the player character will shift one pixel to the right and one column of pixels will seemingly disappear when that happens. on another project, the player will shift one pixel to the right and one pixel will shift from one side to the other when the player sprite moves...
