hi simo I had the same problem . it can be 2 problems, first your videocard. make sure your videocard has open G installed. or your videocard must be 3d videocard with at least 128 mb ram. not integrad videocard. or onboard videocard. second it is from image (pixels) go to adobe photoshop and change your image little bit in size or in pixel and safe it to different format. that helpt. happend to me the same, myn was videocard. I change videocard and fixed the problem. but if you useing laptop than forget it(sorry) because you can not change it the videocard, only if you buy the new laptop with 128 mb ram, i have laptop .I bought it for $2000 and i Did not know it was integrad videocard(onboard videocard with no ram memory) so i have alot problem with maya like (bumpmap-imageplane-rendering freez)
i try everything but nothing help. just change the computer or videocard if you use desktop. good luck
