Anything is possible, so you will need to conduct more diagnostic tests if you want to try and narrow down to any specific cause. Start with Safe Mode:
It may take you multiple attempts to get the ESC key sequence (press/release/hold) correct, so be patient. When successfully into Safe Mode, see what happens.
If the behavior ceases, then think carefully...what happened just before this behavior started? A new app? An update? A Theme? Something else? Think carefully as the smallest change could be causal...and attempt to undo whatever that was.
If the behavior continues in Safe Mode, then something else is the cause (OS Corruption, physical damage, etc.).
Good luck and let us know!
