Help; Pc gets choppy whenever im playing a game and open another app over it

I want to preface this with 2 things; 1. i have no idea if this is the right subreddit to ask this in 2. i know jackshit about pcs, i bought it so i could play warframe

All i know is this; Amd Ryzen 5 4500 6-core processor Amd radeon Rx 6400 ram 16

Onto the issue; For about two weeks now my screen starts getting choppy almost always when i open another app over a game im in. Be it discord, overwolf, or even my browser. Its not an issue with a single game, but with multiple so far, It has happened with every one i opened at least once. This does not happen if im using just my browser or discord. No new installation were done, and nothing comes to mind that couldve started this. Screen gets insanely laggy/choppy and does not get fixed unless i restart my pc which im aware has slowly been killing it. Pc is less than a year old, had no prior issues, bought prebuilt. Ask me anything thats needed, as im unaware whats actually important to mention

The only other mention of this exact issue i saw was someone having a lack of ram if i recall correctly and i dont think thats the issue here, feel free to correct me
