That blue/grey background and the error message generated by
"tooltip::tooltip configure" are caused by some bugs in version 1.8 of
the tooltip package.  These bugs are now fixed in the latest tooltip
version 1.8.2.  I suggest you to check out this new version, in which
the default tooltip background is lightyellow (again) and
"tooltip::tooltip configure" works as expected.

 Thanks, I just downloaded and installed from trunk and the background in
lightyellow.
 Incidentally, before installing Tcllib and Tklib I always have to edit
installer.tcl to add the line
 tk scaling 1.67
 I wish both contained this so I wouldn't need to:
 if {[info exists env(TK_SCALING)]} { tk scaling $env(TK_SCALING) }

Tk 9 uses a different strategy for the scaling-related stuff:  On X11 it retrieves the display's scaling level (100%, 125%, 150%, ...) from the system settings, assigns it to the public variable tk::scalingPct, and passes a value derived from the latter to "tk scaling" (see "man n tk_scalingPct").  Both $tk::scalingPct and [tk scaling] are used at many places in the Tk code and library scripts to make the widgets and standard dialogs scaling-aware.
Out of curiosity:  What is your desktop environment (GNOME/KDE/Cinnamon/MATE/Xfce)?  What is the display's scaling level? Are you using Xorg or Wayland?.  What are the values $tk::scalingPct and [tk scaling] immediately after starting wish?
