No, but after thinking about it, I now suppose that what occurred is the following issue, which I can reproduce with apt install --reinstall linux-image-6.1.0-18-amd64 linux-headers-6.1.0-18-amd64 (which recompiles the drivers, so generates some output). It is possible that I had selected some text, so that this text was in reverse video, then I forgot about it. But when there is output, some other part of the text becomes in reverse video, hence my surprise about random text being in reverse video when I was scrolling backward. I can reproduce that. It seems that this happens as soon as the selection reaches the scrollback buffer. Note that the range of columns of the part in reverse video remains the same, and despite the change of the text in reverse video, the selection remains the same when I paste it. Unfortunately, I can't reproduce the issue with a simple testcase. > b) were the characters in the scrollback supposed to be reversed, and then > incorrectly reset? The reverse video disappeared. But if this is the above issue with the selection, the selection automatically disappears just by clicking in the xterm, which I might have done. > c) is this with bitmap fonts, or TrueType? Vector fonts, so TrueType? But I can reproduce the above selection issue with bitmap fonts too. > d) there's no screenshot or other clue to see how to proceed. The above command should give a hint. -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
