I followed the discussion on the net a while back regarding TmpRas and
AreaEllipse. If I remember well, the conclusion was that TmpRas should
be as large as the largest areafill (or ellipse) you are going to make,
plus 16 pixels. This is exactly what I'm doing. Despite this, I sometimes
get a GURU 82011234 (gfx: emergency memory not available) when drawing
large ellipses. Does anybody have any clue as to why this is happening or a
suitable work around?
By the way, I assume Jimm's 'work around AreaEllipse bug' in his custom
gadget example in the Atlanta DevCon disk fixes 'jagged' ellipses that
sometimes appear. I also have that in the code.
One last thing: under 1.3 it seems that an OpenWindow() on top of another
SMARTREFRESH window can bring down the system in low memory conditions with
a GURU 81000009 (Free twice). My impression is that Intuition (well, maybe
layers) crashes when it can't allocate Chip mem for saving the layer
background, trying to abort the operation and freeing the memory it didn't
get. Is this long known stuff or should I still post a formal bug report?
Any known way to determine a safe memory threshold when opening windows???
