This screen glitches came out of nowhere and it is annoying.

The problem has occur since yesterday. I have to press anything on the keyboard to make it stop, but even then it is still occur like randomly.

I don't know what triggers it, but here is the video: https://youtu.be/S_KghE3GS1I

These are some info I can give you: - I had Ghostery add-on but I had remove it and the problem still occur - I have this problem with the old Firefox version (latest update is 2019 version) and after updating to the latest version 79.0 (64-bit) the problem still occur - Previously the setting was using hardware acceleration, but after unchecking it the problem still occur - I have clear cache and it's not solving the problem - I have connect and disconnecting the WiFi connection and it is still there - I have restart my PC after all of that and it doesn't solve anything

Please help me!

In your video the optional top menu bar keeps appearing and disappearing. On Windows, Firefox has two keys that will trigger the menu bar to appear and disappear: Alt and F10. You can disconnect the Alt key from doing that to see whether it helps:

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button accepting the risk.

(2) In the search box in the page, type or paste menuacc and pause while the list is filtered

(3) Double-click the ui.key.menuAccessKeyFocuses preference to switch the value from true to false

With this change, tapping the Alt key should no longer cause the menu bar to appear and disappear, but you can still use Alt+F to call up the File menu, etc.

Does that help?
