>>I've started seeing that too, after applying the latest boddle plus the

>>22K (16M machine with kernerlpercent=40, vgasize=1280x1024x8).  If it

the gscreen.ldepth change causes the pc implementation to behave
more like the other terminals, preallocating 3  $vgasize sized screens worth of bitmap space
(if possible) in devbit.c.   this reduces the chances of being unable to create a
window (or move/reshape/hide an existing one) owing to fragmentation
of the kernel heap.  kernelpercent might well need to be increased to
compensate, esp. with a screen size of 1280x1024.  at home, i use kernelpercent=40
with a screen size of 1152x900x8 without much trouble.
