Or it could be a texture memory problem. From the image I can see you are significantly zoomed-out, so Atlas is feeding the gfx card with many tiles, each of e.g. 512^2 or more (sometimes I use photo tiles of 2048^2!) with mip-maps activated, which eats additional n/2^2 + n/4^2 + ... texture memory. I'm conscious that OpenGL access the computer memory copy of the texture if it doesn't fit into the gfx card memory, nevertheless a limit request could be a severe test for a non perfect driver.
