Lately photoshop has been oddly freezing while I am working in it. It will let me press and interact with everything except the canvas itself. The document settings are the same I have always used without a problem. I have updated to the latest version and the problem still occurs. At the same time it sometimes becomes unusable after using the liquify tool. Once I exit, if i try to move the canvas in anyway it jitters back and forth. The only way to stop both issues is to close photoshop and re-open, which seems to temporarily fix it.
