xorg.conf and flash

[The BSD Dreamer]

Some last fall, flash started asking weird in Chromium - seemed to also start 
with 24...suspect its how chromium uses shared memory now?

Basically flash would render and then whiteout...scrolling the page would 
force it to redraw correctly, but could whiteout immediately.  I think I've 
mentioned it in passing before, but hadn't seen anything else on the list 
about it.

So, I decided that maybe its a problem specific to my setup....first I played 
around to see if there were flash settings to play with....had turned off 
hardware acceleration long ago to solve the blue skin tone problem.  Didn't 
look like there was anything else that would do anything.

Then I decided to look at my xorg.conf....after a long process of trial and 
error, I found that removing the option "AllowSHMPixmaps" "True" fixed the 
whiteout.  Though now when flash first renders on the screen its garbage that 
looks like it might be a mash of the unexposed output from various terminals 
on my desktop.  Kind of distracting, but it eventually shows right and is 
usable again.

Wondering if anybody knows off hand of what parameters are good or bad that I 
might look to next, otherwise...I'm inclined to just put up with this 
issue...

here's what my "Screen" section looks like now:

Section "Screen"
     Identifier     "Screen0"
     Device         "Card0"
     Monitor        "Monitor0"
     DefaultDepth    24
     Option         "NoLogo" "true"
     Option         "RenderAccel" "True"
     Option         "Overlay" "True"
     Option         "AddARGBGLXVisuals" "True"
     Option         "DisableGLXRootClipping" "True"
     Option         "Coolbits" "1"
     Option         "CursorShadow" "True"
     Option         "DamageEvents" "True"
     Option         "UseEvents" "True"
#    Option         "AllowSHMPixmaps" "True"
     Option         "BackingStore" "on"
     Option         "TripleBuffer" "on"
     SubSection     "Display"
         Viewport    0 0
         Depth       24
         Modes      "1920x1080"
     EndSubSection
EndSection

My xorg.conf was largely lifted from a friend's setup after he had finally 
gotten X working on his system.  Who was also suffering from the same 
problem, but also has 2 other computers on his desk...so had a work around :) 
  Keeps telling me that I should get Mac.... speaking of which, wonder if 
somebody can figure out a way to use the flash 11.7 for the Mac on FreeBSD?
