--- Comment #5 from Felix Potthast mail@felix-potthast.de --- Created attachment 143426 --> https://bugs.freedesktop.org/attachment.cgi?id=143426&action=edit Test program
The bug is still present for me with mesa 18.3.4-1 I wrote a little test program which compares an uploaded 3dtexture mipmap with the corresponding output of glGetTexImage.
It should output nothing, but on my desktop pc it outputs:
Error in level 2 Error in level 3 Error in level 4
Compile with "gcc test.c -o test -lglfw -lepoxy"
