Commen= t # 3 on bug 10122= 4 from Pierre-Marc Jobin 
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 flag=
ged" but
prior to filling a bug report, I did run the testcase against a debug conte=
xt
(as well as under apitrace) and obtained no diagnostic information whatsoev=
er
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 tha=
t as
it receives the internal format argument. It does take care of mipmap setti=
ngs
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 suspe=
cted
a driver bug if I had been made aware of my mistake in some shape or form.

Thank you again,
PM
