UI Outline color not working when using Render Texture

Hi all,

I just ran into a strange issue and wanted to check if you get the same results, is it a bug or is there something that I am overlooking?

I am building my UI panel and I wanted to add an outline to one of the image elements. This always works fine, but I have never used it before in combination when using a render texture on the image. Here's the situation:

1. Create image ui element and add the Outline script to it.

2. Set image color to black (or anything other than white) and set the outline color to white and enough width to clearly see it.

3. The image should appear correctly, but the moment a material that uses Render Texture is added to the Image component, the Outline color turns black for me, and no longer responds to the color changes at all. I can change the width and height and that works, but it's always stuck on black?

4. Remove the Render Texture material and the outline should come back to normal again.

Has anyone encountered this before and is it something that I am doing wrong or a bug that I should report?

Thanks!
