System Information
Arch Linux - Intel HD Graphics 4000 - Nvidia GeForce 610m

Blender Version
Broken: Blender 2.74 997c0c8
Worked: 2.73

Short description of error
Testing the new features, AO and DOF in blender, then switch to view > camera and moving around the render region the image freeze , and trying to move the frame it re draws or display the image inside the render region

Example

Example 2

Exact steps for others to reproduce the error
go to view > camera - Rotate camera view or move the render region with shift + scroll button

after some test i found that the bug is a result of the "high quality" DOF option

Can't confirm that but looks like another issue caused by poor Intel graphics cards/drivers. Could you start blender from the blender-softwaregl? Will be slow but shows us if this may come from the drivers or not.

Yes, the technique requires quite a few extensions to work, I should probably make sure they are present before allowing the use of high quality.

Run blender from command line with blender -d. Are there any messages?

linux or windows

Antonis Ryakiotakis commented

2015-03-23 19:00:19 +01:00

In any system that has the issue, if both have the issue and you can try it on both then that would definitely help.

Antonis Ryakiotakis commented

2015-03-23 19:01:47 +01:00

I highly suspect that this issue is caused by crappy support of framebuffer objects actually, I'll add a few checks in the code so users can check

High quality is only supported for GL 3.0+ GPUs. Added check that will fall back to low quality for now. 1bee77b77a

If issue persists please notify here.

By the way, looks like issue of original reporter is caused by his system using the Intel card (check the system_info.txt file generated from the help menu of blender to check which GPU is used in your system).

Intel may not support it but the NVIDIA does, make sure you have setup your optimus system correctly.

I Googled it and found that intel does support GL_EXT_gpu_shader4 Link And this is and onld artical probaly before intel hd 4600 so these cards should have these capabilities

Then you obviously need to update your driver. Your System_Info.txt file should have all the info you need there

ok yea found a better driver will test another day with that one and it is available for intel hd 4000 also

Did you build your own version? buildbot still doesn't include the fix.

no buildbot

@Blendify, well then try again using latest buildbot. It should now include the fix.

Probably, but his GPU is different...we mixed the reports a bit so let's keep your issue focused here (don't close the other issue!). Probably solving your issue will solve the other one too, but we are not sure if this is a duplicate yet.

Anyway, keep the Intel discussion here please.

BTW, @Blendify, it would really help if you could verify if #43987 happens with your GPU. It happens on my Intel HD3000 but would be interested to know if it happens with newer GPUs too. Thanks!

cant tell if this has been fixed or falling back on not high quality if it does not support it i think greying out the option is a better idea

tested on different computer

Windows 7-64 bit
Intel HD 3000

I'm afraid I can't understand what the issue is with this shader.

The message is not clear enough and without access to an Intel GPU we can't really hope to solve this, since I'd have to do many compilations of the shader to see what works.
According to the specification there should be no error, so this is yet another driver quirk which we'll have to work around by figuring out what makes this specific driver reject the code.
It's possible that the "in" keyword before "vec2" confuses the driver but there is no other way to differentiate between geometry shader inputs and outputs.

Frankly, I have no idea what to try remotely without access to such a system.

I'll have to archive this for now and it might be fixed when I get my hands on such a GPU (or if another coder with it can figure out what the issue is). I'm willing to give directions to the files and code if someone can help with this.
