Windows Client Crashes During Champ Select [Crash]

I play on Windows and recently during champ select (approximately in 1/3 games) the HUD will bug out. I am relatively sure this has been occurring since 6.19, but I cannot be certain. At least that was my first encounter with the bug.

This is a rough idea of what the HUD does: The map will generally leave The textbox looks different, generaly shifted left The Role keyword is messed up and shifted left The Rectangle that houses the runes and masteries goes blank, if you hover your mouse over them they will appear back Various words are missing

Then one of three things will occur: 1.) The HUD will slowly fix itself (only ever the runes, masteries, and summoner's) and not crash. 2.)The window will appear that an "error has occurred and needs to close". Rarely does it say you can wait for it to respond, and in no situation has waiting for it to respond worked. 3.) I ignore the issue, don't touch much and hope the game loads before it crashes. If this happens, I will still have to close out and log back on, but at least I am still in the game.

This has happened to me several points, but it is to the point at which I have left my ranked champ select twice, forced to sign the leaverbuster message, and I can only assume lost 10LP for it. I've never had an issue with leaverbuster before, but I am now punished for the glitch. I have never had this issue with the same computer playing League for 4 years, this seems like a new bug.

Thank you.
