This was a problem I've encountered several years ago, but since it could be neglected then I repressed it.
Yesterday it appeared once again and now it is crucial to be solved. The problem is that I cannot use GL_LINEAR (minification/magnification) filtering on textures with GL_R16UI internal format. It seems like GL_NEAREST is used instead. Is it something common and normal, or I have some other problem in the application? Did anyone have a similar issue?
Thanks in advance!
