For some reason, Rush has been really laggy. When I play a video, it's really blurry. Sometimes when I try to import a video it's stuck at "Preparing Media". Sometimes my video doesn't play when I play it. This has been a problem for me since I just downloaded Rush. I tried to reinstall Rush but it's still really laggy. I've tried switching devices, but it's still super laggy. This has been a big problem for my video editing.
