<pre>Nicolai,
First and foremost, I wish to thank you for your time and support.
I applied the fix you recommended and now, the testcase behaves as expected.
You mention the incompatible filtering parameter "condition being flagged" but
prior to filling a bug report, I did run the testcase against a debug context
(as well as under apitrace) and obtained no diagnostic information whatsoever
about the texture lack of completeness.
I understand that integer textures are incompatible with filtering settings
other than GL_NEAREST but I did expect glTextureStorage to take care of that as
it receives the internal format argument. It does take care of mipmap settings
afaik.
As a suggestion, would it be possible for the driver to at least generate a
ARB_debug_output message when linear filtering is applied to an integer
texture? (especially since this is a default setting) I wouldn't have suspected
a driver bug if I had been made aware of my mistake in some shape or form.
Thank you again,
PM</pre>
