sys/dev/ic : pcdisplay_subr.c vga.c
Log message:
Sprinkle spltty around code which plays with either the video memory or
the backing store. The state of a VT is only coherent if both the active
flag and the backing store are in order, which is not the case during VT
switches.
This fixes display glitches occuring during VT switches if one of the
VT involved is doing a lot of tty updates.
Noticed by deraadt@ on a machine too fast for mere mortals.
