Thanks Basj,

The problem persists across full reboots, so I'm going to say that restarting Explorer doesn't resolve it.

I have partially resolved it for my usage scenario (by getting rig of the taskbar autohide – so at least it's not painting in the default button and messing with the height), but that still results in the clickable area to launch the start menu being a thin sliver to the left of the start menu.

Two updates on my experience, Basj;

The failure to recognise the cursor's interaction with the start button applies to the stylus (wacom drivers) but does not apply to the cursor when driven by the trackpad.

The failure of right-clicking the taskbar to provide the Start11-provided context menu only applies on the first right click; repeating it, the correct context menu shows.

The upside down image is caused by the data in the metadata of the image which can be fixed in an image editor, but the stretching I don't have answer for. I have a lot of trouble making images fit the way I want. There needs to be a way to turn off the algorithm that controls the image size. I have marks on my monitor bezel for the four corners of the Start menu and will do screen capture the exact size of the Start menu, but it never displays correctly, with either Stretch to show entire texture on or off. It would be nice to get an explanation of how this works. (hint, hint)

I am not talking about reboot, I am asking about just restarting Explorer.exe after the issue appear. From what I understand, the issue appear when you change orientation from vertical to portrait (table mode) yes? So, when the issue appear, and you restart explorer.exe does the issue still appear?

When the issue appear, do the restart Explorer.exe while you in tablet mode, does it than recognize the stylus click?

I understand this will not resolved your issue, just something I wanted to test out, and pass it to Support.

Thank you,

Ah, sorry.

In my attempts to recreate the issue, I couldn't remember the original setting that resulted in the double start button, so haven't been able to recreate the full originally-observed observed behaviour. As such, the only part of the behaviour that I can recreate is the failure of the start button to respond to the stylus' presence; this is the case in both tablet and normal laptop modes. It does, however, respond to the touchpad-driven cursor normally.

The situation appears to be more convoluted that I thought. The main problem is the interaction between the stylus and the start button; an interaction that does not occur when using the touchpad. Also, that problem is not restricted to tablet mode. While this might seem to be a stylus driver problem, it only effects the start button, not other elements. I also deactivated Start 11 to test that; the start button works normally in this instance.

What makes it a little more convoluted is that when I revert to the default Windows start button icon within Start 11, the start menu gets seriously messed up, sometimes launching both the Start 11 one, sometimes the Windows one, switching between them on a subsequent click, or both launching together (Start 11 underneath).

I know this is confusing. It took me a lot of attempts to make it this clear.

Perhaps, making and posting a video on it might help explaining it easier.
