Am I allowed to resize a TBO after the fact? That is, am I allowed to provide a buffer (with glBufferData and the DYNAMIC_DRAW flag) which size is different than the previous one?
With my nvidia setup, things work correctly when I do it.
With my AMD setup, buffer uploading with glBufferData works correctly. However, the data I try to read with texelFetch() in GLSL at a given location seems to be wrong, if this location is beyond the size of the original buffer, .
