i don't recall the specifics but in many cases of black trees or blocks instead 
of trees, the solution has been to reverse the current setting of anti-alias... 
if it is on, turn it off... if off, turn it on... idk why this is or why it 
seems to work... i'm not even sure, ATM, which anti-alias setting to change 
because there's two available... one in FG and one in the GPU driver tool but 
this may also be affected by driver override settings...

in any case, i've seen it on NVIDIA GPUs and flipping at least one of the AA 
settings has always corrected the issue... i've had to do it enough times over 
the years that i don't even recall what the defaults were :lol:
