Created attachment 373302 [details] screenshot showing that the Transfer column is not visible For some account, the Transfer column is no longer visible (see attached screenshot). I've tried to resize columns, but this does not make it reappear.
In .local/share/gnucash/books/comptes-vl.gnc.gcm, the transfer_width value was set to 1 for this particular account. I could change this value manually, so that I could get the column back. Note that with a column width of 1, one cannot double-click on the column to adjust its size, in particular on a HiDPI screen!
