So I know there have been posts about issues on Windows 11 and 3.30+ with extreme lag, glitches, etc. and people say to go to 3.29 and delete X file and Y folders but its not making any difference. I am having issues on both Mac with a M5 macbook pro and my windows desktop. Extremely high CPU usage, memory leaks till its using it all and steady disk IO on both. I just recently moved to Spark on iOS and it's a fantastic app there now that I got used to using it. However now only to find out either desktop app, spark classic on mac included are just basically trash and unusable.

Has anyone found a solution?
