My guess is it's a problem with display settings in windows. You might need to change the scaling. Start, settings, display change the scaling to whatever will make it fill. Shrink the Studio one window(don't minimize just make it small). Try switching the scaling back and then try maximizing the window. May or may not help. The choppy sound is probably because of a couple of things...But more than likely it's the sound card settings, In studio one click 'Studio One', 'Options', 'Audio Setup', under 'device settings' raise the block size. Make it huge something like 2048. There's a tab just above that I don't remember what it says but click on it. It should have the option for drop out protection set that to 'maximum'. And this point hopefully the track will play. These settings are awful for real time playthrough but for playback isn't a big deal. And lastly depending on the arrangement you may not have enough ram. 4GB is a small amount these days. If it's not soldiered in your laptop I would suggest upping it to 16GB, but depending on what you're doing you could get away with 8GB. Good luck
