Java screen glitch

My Mac is currently running OS Catalina (10.15.4), although I've had the same problem with the previous MacOS. Java is also up to date (Version 8 Update 241)

Whenever I launch the java menu within the System Preferences, the whole screen starts to glitch uncontrollably (screenshoot below). The same problem also happen with any other software that uses Java (i.e. PokerStars). What's interesting is that even when I uninstall Java and try to open the PokerStars, or any other that I believe uses Java, the same problem happens.

I've already trying uninstalling Java with the Java Software provided by the website and then reinstalling, but had no luck. I've also tried to twitch some options in the Java menu, but nothing seems to change.

Any suggestion would be appreciated.

A Few Thoughts:

Restore from a Time Machine Backup:

Did you back up your Mac prior to installing this update? If so, restore from it, seeing if that fixes this. This is a pure example of why to backup your Mac prior to any major change to your system (update being such a change). How to Use Time Machine: Create a Time Machine backup of your Mac, so that you can have something to restore your Mac from, should anything go wrong with the reinstall.

If that is of no option, then..

Isolate the Issue:

Reset the SMC and NVRAM: Restarting your Mac and then reseting your SMC and NVRAM.

Create a New Administrator: (Go to: System Preferences > Users & Groups).,Sign into it and see if this still occurs. If not, then it is something configured in your current user. So, transfer all your files to the new user, rid of this current user, and use the new user from then on. You should be set to go.

Boot into Safe Mode: If of no success, then boot into Safe Mode (Hold Down: Shift key upon boot). Caches and all other unnecessary items are put aside when logging it. So, see if this still occurs.
