[GamePlay] Flash becomes gray and unusable?(Possibly hex flash related idk)

i was playing a game of maokai and eventually after a while i noticed that for some odd reason my flash was grey. I know that it might sound random, but i think hex flash is responsible for this. This link will take you to an image on how it looked on my view https://cdn.discordapp.com/attachments/539299218188402689/551327008739688468/unknown.png
