Package: xserver-xorg-video-nouveau Version: 1:1.0.16-1 The problem is that there appear (graphic/video) glitches/artifacts in opera and chrome browsers like never before.
I guess that is due to the old nvidia video adapter and the driver nouveau. The system (2006 year - amd athlon, ddr2 4GB) is with built-in Nvidia nForce 430 / GeForce 6150SE (chipset/video adapter) and debian buster (10) latest updates with lxqt/sddm/openbox (LXQt 0.14.1-1, sddm 0.18.0-1, openbox 3.6.1-8 and Qt 5.11.3) on kernel 4.19.0-10-amd64 (4.19.132-1).
