It’s not redrawing the frame, it’s more related to aligning the monitors refresh rate to the frame rate of the content being displayed. Alignment means your monitor doesn’t refresh the screen when the frame is only partially rendered (aka screen tearing).
Don’t give up, try a scrapper if the finish sits on top of the vaneer. If the finish soaks into the vaneer and you don’t want to sand through, you can always sand back a bit and then use touch up markers with a fine tip using a close match to the wood grain colors shades to mimic the wood grain pattern overtop of the stained sections. Then reapply finish. Or just live with it as others have said. You are hyper critical of your work but others who admire and don’t know about the “mistakes” likely wouldn’t notice and/or care.
