Blank window popup

Hello everyone,

I am using a MacBoook Pro currently and have started to notice a blank window pop up on the home screen. It happens on and off and goes away only when I shut down the computer. Can anybody tell me why this is happening

what should I do?

Untitled Window with Red Spinning Circle Hey everyone, I've been having an issue for the last few months with my MacBook Air. Upon launching certain web pages (one that I know for sure causes it is when I log in to Quickbooks Online), a blank window with a red spinning circle in the middle pops up over the page. I have to click back onto the web page to continue, but the "untitled" window remains in the background. There is nothing in Force Quit, as you can see in some of the screenshots I've grabbed. I cannot close the windows except by restarting my Mac or sometimes quitting certain processes but that usually causes other things to quit and reload. I'd like to stop this issue once and for all because it's extremely annoying when I have to continually click off of them to use my Mac. See attached screenshots below. Let me know if you need any additional info, etc to get to the bottom of this! 2019 MacBook Air running Monterey 12.1 and using Safari as web browser (issue has persisted over multiple updates)

Black bars appearing above Finder windows. Hello Mac Community! Anybody else getting these weird black bars appearing above their Finder windows: They just started appearing like a week ago, out of the blue. I am running the latest version of Mac OSX High Sierra 10.13.5... See, there's the black bar again, just as I went to check my OS number. Any thoughts? Thanks!
