There are almost a screenful of blank lines being inserted when the screen = is being resized. This does not create an impression of careful programming, in particular wh= en also taking into consideration that old output is being overwritten at (possibly random) positions (see PR261641: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D261641 ). Instead of this behavior, the output should just be continued where the cur= rent printing position in the console was before loading the drm-kmod driver. --=20 You are receiving this mail because: You are the assignee for the bug.=
