Lenovo Chromebook 300e 2nd Gen has touchscreen action reversed

Using a new Lenovo 300e, the action using the touchpad is correct but the mapping on the touchscreen is reversed. For example, when using Canvas and the screen in landscape, drawing a horizontal line at the top of the touchscreen from right to left produces a drawn horizontal line at the bottom of the screen from right to left (with the x coordinates of the start and end appearing to be pretty much accurate). Drawing a vertical line on the right side of the touchscreen from top to bottom produces a drawn line on the right side of the screen but the line appears from bottom to top.

 

The behaviour is easy to see in Canvas but exists when using the touchscreen in any other application as well. A tap or drag on a web page is translated to a tap with the wrong coordinates to the application.

 

I have found an open issue in Chromium that seems to have a very low priority for fixing (https://bugs.chromium.org/p/chromium/issues/detail?id=969472) but this seems to me to be a fairly serious limitation of the touchscreen functionality. Has anyone else experienced this? And is this a Lenovo hardware problem, or a Chromebook OS problem?

Thanks. Resets were ineffective. It was apparently a defective unit and had to be sent to the warranty depot for repair. Hard to believe a logic problem this severe made it past quality control but it's returned and working now.

 

And we're back...
