It is possible that your GPU has an unstable clock and/or is overheating due to the additional frame rate it is pumping out with the new update. Try using a frame limiter to limit your FPS (you can adjust it to limit to 1500 or whatever you like in your osu! config) and see if it helps.

To do this go into your osu! folder, open "osu!.<your windows username>.cfg", then change "CustomFrameLimit" to whichever value you like.
