on bug 67981
from Alex Deucher
As mentioned in bug 51658, r1xx/r2xx hardware supports texture formats that cannot be rendered to: "> r200 essential patches (1st 3 patches) for gnome shell: > "Essential patch to disable texture formats that are reported unrenderable > elsewhere in driver." I'm not really happy with that. I guess the problem is if we try to attach a texture to a fbo it is too late to notice we cannot render to that format. But this sort of sucks for ordinary textures. Ideally we'd probably be able to really determine our format only at the first upload of data to the texture (which presumably won't happen) so we could change it if we attach it to a fbo. Though if there is indeed already data uploaded we're screwed." You could try applying attachment 63711 [details] [review].
