Blender Version

Broken: 2.71.5 e2c412f (example: 2.69.7 4b206af, see splash screen)

Short description of error
When a texture is added to an object it doesn't appear in Texture Mode when shading is set to GLSL, and errors appear in the command line.

Exact steps for others to reproduce the error
Based on a (as simple as possible) attached .blend file with minimum amount of steps
Open the file and the error will appear in the command line. It also appears if a texture is added to an object in Texture mode.

I have the same issue on Arch Linux 64-bit, ATI Radeon HD 7660, with Open Source drivers. Error message with -d flag . Blender 2.71 GLSL works fine.

Windows 8.1 on the same machine doesn't have the problem at all, oddly enough.

Can we see your system_info file? generate it from Help menu ->system info and then open a text editor and browse for the file at the drop down menu in the footer.

@Emolga can you confirm if 2.71 works for you too?

Here's my system info file.

Also 2.71 works.

There's little here that looks suspicious.

@Emolga, could you try running blender from the command line by opening a command line, changing to the blender directory and with running the program with "blender -d" like @xrg does above? It would help to know if your error is the same.

Also is that the latest available driver you are using?

The weird thing is that the error @xrg posted makes no sense because the error message is contradicted by the code :/

Here's what I got from running from the command line with "blender -d"

command.txt

And I updated my drivers are up to date.

Just added debug information for shader limits in OpenGL in 85945a8 . It should help us debug the error better. @Emolga, from you I'd like to get a build from builder.blender.org tomorrow and regenerate system_info.txt . I suspect we may be hitting some implementation limit here (unlikely, but may happen). If I see nothing suspicious I'll try disabling the clipping workaround and see if that helps.

Hi,

Thanks, but the current builds won't include that commit. Builds are done per day, usually at night, so you have to wait for a day to get an updated build with that commit (that's why I asked for a test with a build tomorrow). For reference, here's how a good file should look like ("good" means you should get an extra "Implementation Dependent OpenGL Limits" section at the end of the file. system-info.txt)

System-Info for me (built from source).

Edit: I checked a LiveCD of Ubuntu and it has the issue there as well (so it doesn't seem to be a configuration problem on my part). What a bizarre bug.

@xrg tested on firepro - windows 7 at institute and can't reproduce :/. Shader limits are the same so it must be something else. I see you compile from source, would you be able to test a patch from me, see if the issue is resolved with it?

xrg commented

Sure, that shouldn't be a problem.

This will disable a recent workaround that I added to ATI cards to support clipping, let's see if that makes things better. clip_workaround.patch
Thanks for the help!

Ah, that patch fixes it here. Very nice. :)

@xrg,Can you try this one too {F107304}? I hope this works because the previous patch disables this fix #40981.

Seems you solved it (well at least on Linux). That patch fixes this issue, and clipping border with matcaps works.
