A recent upgrade installed the new version of Firefox: 78.15.0esr. It was released on 5 Oct 2021.
It has a very annoying behavior and I wonder if others experience it. I have torbrowser installed. It works fine, and so I don't think it is a problem with X window system. I purged Firefox and reinstalled it with no custsomization, and it still showed the behavior. So it seems part of the Firefox release itself. The behavior is hard to describe. When I scoll text up or down by using the arrow keys, the lines of text begin to break up and become unreadable until they settle about one second after the scroll ends. Actually it is thin horizontal white lines less than a cm wide that last a second. Nowhere else do I have this problem with scrolling. Another symptom: when the cursor is moved to or away from the scroll bar, the grey scrollbar is broken into a vertical set of grey and light grey lines for about a second. When I drag the scrollbar to scroll text, text and images are broken up by horizontal white linees for a about a second. In a colored image these lines can be colors from the image. -- Haines Brown _______________________________________________ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
