[mac] Screen / Texture Flickering

Hi all,

I'm running PoE (via Steam) on my 2018 MacBook Pro, and I've noticed an issue that pops up roughly once a day. I'm not a tech guy, but the best way I can describe is that it looks like the machine's GPU is giving out--one moment the game is running fine, the next the game's textures are flickering like crazy.

I've captured the issue twice via screen recording:

Every time this occurs I have to restart the game completely to resolve the issue. That said, I've had it happen on maps, during Sirius, etc,. *mostly* during intense sequences in the game. For what it's worth, I've never had it happen while decorating my hideout.

So, I guess my question is this--am I the only one experiencing this? If so, how can I go about reporting it to the proper people to get it checked out?

Any help / guidance is greatly appreciated. Thanks, and stay safe exiles!

Best,
wk
