Please see two images, captured from Aximmetry's Open Space Scene template. You will see on top of the backdrop angled lines in a pattern. If you look (zoom in) more carefully to the rest of the screen, you'd see faint presentation of such a pattern elsewhere too. What could be the reason for this phenomenon and how to avoid it?
Hi,
It is most likely part of the image that was added as a Background Image:

Note, in the Background Alignment panel you can rotate the background and change where are the image's two ends are stitched together in the virtual world.
Warmest regards,
