epic-games-store under Lutris black screen after every update/upgrade

[MajorGonzo]

Hello. I hope this is the right place for this. I installed your branch for mesa to run corectrl (thanks for that, btw). However, since then, it seems every time I have an update that includes the mesa branch, Epic Games Store, when launching from Lutris, just has a black screen in it's window (still has min/max/close buttons) and the loading bar across the bottom (blue swirl line). If I reinstall Epic Games Store, it works again. Not a huge deal, since there's a workaround, but I'm willing to work with you to figure out what's wrong. Happened again this morning, so I grabbed the --upgradable and upgrade screen messages to see if this is even connected at all to this branch. What do you think?

Hi!
This is not related to this specific ppa, just with updating Mesa in general I would say. Perhaps related to the shader cache?
