I think I've seen reports of this before - it looks like it affects a small number of older devices with some specific hardware/driver configuration.
It looks like either a graphics driver bug or a bug in Chrome's WebGL implementation. The error refers to a D3D shader compilation error, which is probably happening inside ANGLE, Chrome's internal graphics library that converts WebGL to D3D. Like all other WebGL content Construct makes WebGL calls and uses GLSL shaders, so it does not directly use anything in D3D - that's all generated by ANGLE. And if anything Construct does was invalid, it would have failed earlier, with a WebGL or GLSL error message (and probably affect other systems too).
I think the best thing to do would be to report this to Google at crbug.com, showing that error message, and including details about the hardware of the affected device.
