2021.1 Instability Issues

Hello, 2021.1 has serious instability issues for me. I am restarting Rider a few times a day and I'm getting ready to uninstall it and go back to 2020.Before I do I figured I should reach out. I don't know how best to give support feedback, but the main problem being that the main editor tab no longer updates, showing a cached view of its graphics buffer contents. If I open the Goto Anything window it will refresh the window. The scroll bars scroll. One of the more odd behaviors is that the close 'x' in the upper right no longer closes the solution, but closes the buffer open in the current tab. So in order for me to restart I must close out every tab I've opened before closing the solution. Truly odd behavior!

I'm on Windows, generally working with Unity, Perforce, and Git. I work in Distraction Free Mode, without tabs and most palettes are not docked or open. I usually have two editor tabs open. Hope this helps...
