Try playing with the screen settings. Just make som random arbitrary but large scale change that requires a monitor refresh. Then revers the change. Worked for me.
I lost a disk load notice and no matter how many windows I closed (all of them) I still couldn’t click on the pop up. This method solved it.
there are multiple display/windowing system related bugs at the moment.
