Laptop Dell inspiron 15 3000 RAM: 16 GB SSD 480 GB Kingston Intel Core i3 7th Generation OS: Ubuntu 18.04.4 with Software and System Updates Web Browser: Mozilla Firefox, Google Chrome, Palemoon. All latest. Terminal emulator: Yakuake, gnome-terminal. Other Terminal: TTY1 Internet service provider connection speed: 100 Mbps (asymmetric) Full upgrade: march 23, 2020
Just recently noticed that my mkv videos stopped working just after a system upgrade. That's why I requested help here: Error on videos (.mkv) after software upgrade. And the problem was partially solved.
Nevertheless I didn't notice that some other video overlay functions stopped working, like the overlay video which is used by AnyDesk to create the remote control session. Please see this screenshot.
Just entered the Ubuntu default desktop environment, and I noticed some weird green color artifacts on the desktop, which won't render on the top of the windows, just on the desktop.
Can somebody please help me to revert or fix the problem the upgrade created?
If you need further information please let me know. I don't know where to start the investigation and what I would do is to reinstall everything. But I would prefer not to.
Thanks in advance.
