System Information
windows 10, intel hd4600
Blender Version
Broken: daily build 2.79
Worked: (optional)

Short description of error

Blur node with Relative checked, result differ from pixel mode. Relative calculated for X as (pixel blur size / render resolution X * 100), for Y (pixel blur size / render resolution Y * 100).

When I check back and forth from Relative to Pixel mode the result is different, relative looks stretched Y direction.

Do you mean that there is a problem with aspect correction ?

Your description is not sufficient to understand if there is a deisgn issue, a misunderstanding of the feature or a bug.

Thanks for the report but it would be helpful if you add a blend-file to the report that demonstrates the issue at hand.

Can you provide a .blend file containing a blur node with relative checked and a blur node with relative unchecked connected to split viewer node ?
So, we could see what node sets you expects to work the same.

Well. I see no difference in .blend file under linux.
Maybe the bug is specific to platform.

I am waiting for confirmation from another windows user.

With provided file I can see the difference on WIN7 64bit. But if set blur percentage at 0.6 for both axis and choose Y correction, then I see no difference.

The only difference I see on my system is that the width of the relative blur is one pixel less. This behavior is that the percentage is rounded by casting the percentage (float) to an int.

I can confirm the problem mentioned by @jbakker.
The problem seems simple to solve.
We can use round_fl_to_int instead of casting directly float to int.
