I was just plodding along, just started a new piece, went to insert the background from a separate image and it did so, but somehow created... tiles of the drawing? i mean, there are rows upon rows of miniature versions of my art, like there is a "tile" function or something. I have no idea what happened and no idea how to fix it. Already undid all I could undo, but there was no effect on the tiling. The only thing I can think of that might have done it would be the "clones array" but there's no way to undo this as far as i can see! on a lenovo thinkpad with a wacom intuos, windows 10 beta mode. i can give screenshots and more information if necessary. please help!

You are using Windows 10 beta on a Lenovo Thinkpad? These forums are primarily for topics related to KDE's Plasma desktop and related software. While the problem you describe doesn't seem to be related to our software, we can try to steer you in the right direction. You might also want to ask in other forums dedicated to Windows, esp Windows 10 where you should get more specific assistance for any problems you encounter.

So, you were fiddling around with images, trying to set the desktop background and now the desktop background has some image tiled in a grid pattern across the desktop background?
Or was this in some drawing application that now shows a new picture with the image tiled across it?

If it is the desktop background, you should be able to right-click on the desktop and go into the desktop/background settings where you should be able to change the background and/or change the display options for the background from tile to stretch/fill and it should display the image stretched to fill the background.
