Additional Information

In Electron version 37.X.X this issue appears to be nonexistent. I was also unable to reproduce it on MacOS, which appears to still function the same as it did in version 37 of Electron. We have found similar issues under some versions of Linux with KDE, but it's hard for me to say whether or not they are directly related. Which leads me to believe this is a Windows-specific problem.

Though the testcase Electron Fiddle project loads an image from a web location, the issue also seems to occur with bundled assets called through the require(...) function.
