Looking at your link to Wikipedia, it does indeed seem to have something to do
with Mesa (there's a paragraph in there about 'shader'). But I've never heard
of Mesa, and I certainly didn't install it.
This sounds like one vote for deletion. Or maybe .8 votes:-)
Mesa is installed by default very often, in many DE. Certainly is on
mine, I know because I use it.
Applications which use OpenGL to draw like browsers or multimedia
programs may also use it, it's not only for games.
Quick 1 minute DDG search, second link, reveals:
"basically, any application which uses OpenGL (Mesa) might try to use
the shader cache directory."
If you delete this directory, probably it will get recreated.
Check what mesa packages you have installed:
dpkg -l | grep mesa | awk {'print $2'}
