Texture & component previews stop showing correctly when project left open for a while

Found issue:

I've run into this issue few times now that Texture image previews (in Material Browser or Texture Editor) and component icons (in Components View) stop showing correctly. It might have something to do with time, since usually this happens when I've had some project open in Design Studio for a longer time -> I close it -> open some other project -> textures previews and component icons are not shown correctly.

Steps to reproduce:

• Open Design Studio and some project
• Leave it open for little over 10 minutes
• Close the project (but not DS)
• Open e.g. Material Bundle from examples
• -> texture images and component icons not shown, see picture.
