Linux hosted, refresh problem.
From AROS home page:
Note
Unless you are running XFree86 3.x or earlier, you may notice that the
AROS window does not refresh properly (for example when a different window
passes over it). This is due to the fact that AROS uses the "backingstore"
functionality of X, which is turned off by default in XFree86 4.0 and
later.
To turn it on, add the following line to the device section of your
graphics card in the X configuration file (commonly named
/etc/X11/xorg.conf, /etc/X11/XF86Config-4 or
/etc/X11/XF86Config):Option "backingstore"
A complete device section might then look like this:Section "Device"
Identifier "Matrox G450"
Driver "mga"
BusID "PCI:1:0:0"
Option "backingstore"
EndSection
I don't want, or have time go get into detail. I just had some trouble last days with Lubuntu. Problem is that no matter what I did it I could not get the backingstore function to work.
I had to try other Linux distributions. Ubuntu works nice but is slow as hell with my old laptop. Other lightweight Linux distributions like "Absolute Linux" or "Bodhi" gave me other problems. End of story is that I finally found a Linux distribution that works great with AROS64. The Linux distro is called "Peppermint". It even got the the Amiga colors and the logo look Amigaish :)
Other good news is that you don't have to use the "backingstore" option. It works out of the box. Now it is time to play around with AROS64 again.
