Ringhio vs MUI bug

After the Ringhio notification box disappears off a MUI screen, it leaves a rectangular shadow where it had been.

This must be a Ringhio issue, because all other windows on a MUI public screen restore the background correctly after moving/closing. I cannot tell what Ringhio is doing in this case, but the MUI public screen has a backfill hook to restore the intended background which gets called as soon as some portions of the screen become visible again. Complain at A-EON about this bug.

THis kind of thing occurs on public sreen, with compositing effects turned off, when the palette is updated after the screen is opened, and the backfill hook is clearing using the background pen. (which the default does).

Iy used to happen with AWeb until I fixed the way the paletter was loaded. Though I can't remeber exactly what I fixed. I'm sure it happened with YAM once too, but can't reproduce it now.

I'm not saying it's a MUI bug as such, but it is a problem with the program that opened the screen not the visitor window.



It's a side effect of using 256 color palettes on true colours screens.


I had to jump through several complex hoops to get that working properly in PPaint IIRC.
