I had not noticed that you seemed to have added the updated classic textures as I was still seeing the pixel shifts on display. I thought that odd, since it there have been two releases since that point in our discussion. So, I extracted the textures (kodi-texture.exe gui) and had a look at the individual files. It appears that they were indeed updated, but I saw no improvement on display.
I tried a few things, but to no avail. Then I recompiled the extracted textures with no changes made to any graphics files and installed the rebuilt archive. Suddenly everything was fine! Well, everything with the media flags at least. I noticed however that I had re-introduced the one pixel shift (too high) in the poster tags in widgets!
This is very strange, so I thought I would mention it here!
Notes:
I used the kodi.texture gui to de-compile. The original size of the Texture.xbt file is 7955 KB.
I can use either the gui or the command line TexturePacker to recompile (no changes to any files!) and the new Texture.xbt file is 9495 KB. That's odd, but OK maybe we are using different tools (I think the texture compiler changed for Kodi 17?).
In each case (gui or command line) the new Texture.xbt file fixes the media flags but introduces the pixel shift in poster tags.
I have tried rebuilding the texture cache -- no effect.
Any ideas
