Yeah, I've tried googling for this too, but found no solutions either. > it could be that evas uses egl+gles and the nvidia driver implementation for > egl+gles is buggy - you can rebuild efl to use full desktop opengl+glx > (-Dopengl=full). I've deleted the evas cache, and set the compositor to SW to make sure that it's not an evas egl problem. The exceptions are still there. Actually there are 3 exceptions for the kernel thread "[irq/92-nvidia]", and 1 for Xorg. When the compositor was set to opengl there were more exceptions, and one of them is was for the enlightenment process. So my guess is, that this may not be a problem in E, but maybe a missing/extra step during suspend/resume. I'll look into this tomorrow.
