The CURRENT row, with colour attribute set, displays correctly. As the row cursor is shifted down the screen and back up, the 'ghost' of previous display remains, so the first 2 fields appear a mess. If "normal" libncurses is used, the problem does not appear. The problem can be 'fixed' (or rather, hidden) by applying an explicit colour attribute to the display window, even if it's the same as the implicit colour used when no attribute is given. (2) In displaying a window with a border with the top left set at column 3, the border is displayed 1 character space left of the screen fields, so that there is a gap at the left, and the right-hand border is lost. A variant of this problem appears in a couple of instances, where a MENU line is displayed. In these cases, the border round the 3 sides of the menu lines (top or bottom of the screen) are offset left by 1 and the rest of the border displays correctly. The only 'fix' I have found is to shift all windows that were starting in column 3, to use column 2 or 4+ I realise that this may not be a cursesw problem, and checking the source code for aubit4gl is beyond me - but as far as I can see, libncursesw is the only thing that has changed ... My code and screen definitions hadn't changed since before the upgrade from 18.04LTS. Aubit4GL hadn't changed. The changes in libncursesw (and/or panelw, formw) are a prime possible cause of the new behaviour? The Aubit4GL TUI_wide plugin links to libncursesw.so.5 => /lib/x86_64-linux-gnu/libncursesw.so.5 (0x00007f9ac30dc000) --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu27.9 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: mbm 1654 F.... pulseaudio CasperMD5CheckResult: skip CurrentDesktop: X-Cinnamon DistroRelease: Ubuntu 20.04 InstallationDate: Installed on 2017-03-09 (1321 days ago) InstallationMedia: Ubuntu 16.04 LTS "Xenial Xerus" - Release amd64 (20160420.1) MachineType: Dell Inc.
