System Information
Windows 7 (64-bit) / Intel Core2 Duo / 4GB Ram / ATI Mobility Radeon HD 3670

Blender Version
Broken: 2.74 RC2 1f547c1

Short description of error
Enabled the 2.74 feature of Depth of Field for the camera view and zoomed in with mouse wheel corrupted the view-port.

Exact steps for others to reproduce the error
Start Blender and use any rendering engine (Blender Internal, Cycles or Game)
Set a view-port to camera view (perspective) and press 'N'
Expand 'Shading' and enable 'Depth of Field'
Zoom with mouse wheel and view-port becomes corrupted

Attached is the system-info.txt file along with two images (zooming in and zooming out) that show the corruption. I had extracted and used the .zip file version of Blender rather than using the installer.

Cannot reproduce that here (linux64 bit, NVidia GTX850m). Can you please:

Ensure both your OS and drivers are fully up-to-date.
Try to tweak OGL settings in UserPreferences, System tab.
Try the latest build from our buildbot.
Try to start Blender in factory settings (--factory-startup commandline option) (this will ensure whether this is a userpref or addon issue or not).
Try to place this dll next to your blender.exe (software OGL, will be slow, but will show whether this is a driver issue or not).

@Psy-Fi maybe you have some ideas on the topic too? ;)

Yes, this is a shader compilation error.

Fire up blender from the command prompt/terminal with

blender -d

Then enable depth of field and an error should appear at the command line/terminal.

Can you post it here please?

Alternatively you could start blender with

blender -d 2>error.txt

And this should create a file with all the errors in a file named error.txt next to the blender executable. You can paste the contents of that here.

Did you also enable depth of field from the camera view? It's strange that there's nothing there...

Bastien,

I went through your list of suggestions and the only thing that worked was the .dll you linked. It definitely was slow, but DoF worked as intended. I realize my system is quite outdated. Other than the DoF issue, Blender runs fairly well on it. If I disable DoF in camera view, the view-port returns to normal.

So does this mean I have a driver issue? Thanks for your assistance.

Antony,

I enabled the DoF from the camera view and though the issue came up, that text was the only thing I saw from the command prompt. The only success I've had so far was using the .dll that Bastien had linked. I'll try to see if there are any newer drivers that still support my old video card. Thanks again for your help.

Can I see the contents of your System_Info.txt file (generated from the help menu of blender, see contents in blender text editor)? It's possible that your GPU does not support the effect. I added some code that disables it in low end GPUs today, but just to make sure...It's weird because your GPU should support it if its drivers are up to date.

2.74_system-info.txt

2.73_system-info.txt

Attached are the System_Info.txt files generated by Blender 2.73 and 2.74 RC2. There are some minor differences, but nothing I see that would cause the issue. Though I am using the 64-bit version of Windows and Blender, the platform in the text files reports 32-bit.

I've tried various drivers for this video card from AMD with Catalyst 13.9 being the latest driver for legacy cards. This may just be an issue for a few older cards and I have no problem keeping the view-port DoF disabled for the time being. Nevertheless, your assistance is greatly appreciated!

This is really weird, as far I can see the effect should supported. I don't think I can do much here without access to this GPU unfortunately :/

Yes, but that's a different GPU. Also latest buildbot should work for Aaron now?

Dom commented

2015-03-25 02:15:44 +01:00

I tried today's buildbot version and still have the same result, but as I said earlier, it's time I update my laptop! Would AMD's patch help any? I'll look for some 3rd party drivers for this card and see if that makes a difference. I'm surprised it worked with that .dll Bastien linked. It was slow as heck, but the effect was there.

Bastien Montagne commented

2015-03-25 07:42:10 +01:00

The dll is a software emulation of an OpenGL driver, i.e. it behaves exactly as a GPU driver (should do!), but code runs on the CPU instead of GPU, that’s why it’s slow - it features a reference implementation of OpenGL, so it shows actual issue is with the GPU driver, not in Blender code.

The above commit should have fixed the issue for the ATI case (which was different than the Intel case). Reporter should be able to confirm this in tomorrow's buildbot build. If this is not the case we can reopen this report.
