fix: shader error

The shader compilation error occurred in wp_stripes.frag, which handles
the "stripes" wallpaper transition. The bug was
  caused by the modulo operator (%), which is not supported in the older
GLSL version your system is using for
  compilation.

  I fixed it by replacing the incompatible % operator with the standard
mod() function, which works across all GLSL
  versions.
