Hatched areas appear - corrupt layer or Photoshop problem in general?

Question

Hi there,
when I edit a picture in PS, after a few steps (cropping the original layer, content-aware fill, adding some text layers, etc.), parts of the original background layer is covered with a hatched area. First I thought, this could be a display problem, but when you close and re-open the file, the problem remains. And it actually seems to be in the layer - when you hide the layer, the hatched area also disappears.
By the way, I've been working with the CC 2014 Windows edition for a while now and never encountered this problem before. It just appeared yesterday.
Any ideas how this can be solved?
