Oh hey, update for anyone else looking at this: del found a solution!
In steam settings, add launch arguments and set it to:
WINE_DO_NOT_CREATE_DXGI_DEVICE_MANAGER=1 %command%
Yeah I've been having the same problem here too. Using it via proton on steam, and although everything else in the game works fine, the tv is the only thing that I haven't been able to figure out.
I've tried changing the proton version to Proton-Experimental and also using Steam Tinker Launch and changing it to ProtonGE but nothing has really helped with this.
I was coming here to mention the inventory duping glitch I encountered, but I see you've already released an update that addresses that, sooo...
Instead maybe a suggestion for the stacking:
Can you make it so the used batteries don't stack? At the moment they stack with new batteries which makes is a little hard to figure out which to keep and which to throw away if you have multiple.
Other than that, I've loved the way you've been going with the game so far. I'm super excited to see what you come up with next!
