Hi and thx reporting.
For the first issue, I can confirm.
Clone Image draws behind the main Image.

For the second issue, I would kindly ask to open a separate report for this, otherwise it is going to be harder tracking progress on each of them.
I will update this report accordingly.

I am not familiar with the clone tool. I wasn't able to use it in the image editor with the documentation in the manual https://docs.blender.org/manual/en/latest/sculpt_paint/texture_paint/tools.html. (RMB shows me the brush settings). Is there another way how to use it. A prepared example file would also help.

Issue might be related to the more advanced usages of the depth buffer, but could also be related to the GPU depth settings. But without the exact steps I cannot tell where to look at. Thanks!

@lichtwerk explained it to me. Seems to be multiple issues the new draw engines separates the overlays from the images. The stencil image is rendered with alpha blend on the overlay buffer but has a depth test enabled. The depth of the stencil image is set to 1.0. what is behind the displayed image (depth = 0.75)

Solution within the current architecture would be to draw the stencil with depth 0.6 (below the UVs) in the overlay engine. eg: Phase out draw_image_paint_helpers

@lichtwerk for the records, the sample file is a really confusing one for me. To see if a grid is drawing correctly on top of another grid is not ideal.

If we were not that close to the release I would ask a better file.

(to be fair, I managed to get hang of the file later, changing one of the texture from color to uv grid helped me a lot already, that and remembering how to pan the stencil - RMB)

glad to hear, but yes, often times a lot could be a little more straightforward
