[Flightgear-devel] Workaround: c172p on MacBook Pro with Intel HD3000

[Olaf F. <fg...@of...>]

Hi,

on some Mac Models with Intel HD 3000 graphics flightgear showed a really nasty flickering effect.
I had the problem  with c172p and the bumpspec shader effect enabled.

After a lot of investigations I discovered that actually "size matters".  I get this kind of flickering artifacts if  texture maps are larger than 2048x2048, even with a trivial shader prog.

Unfortunately the dimensions of the textures in Aircraft/c172p/Models/Livery
	fuselage-normal.png	tail-normal.png		wing-normal.png
are 4096x4096.

Please resize these textures to 2048x2048, since we do not loose to much eye candy anyway.

Greetings,
   Olaf

BTW:
GL_MAX_TEXTURE_SIZE is 8192 according to
