Hello. I've been trying to run Steam via POM, and it does work, but when it opens, the window appears completely black. I cannot see the store, nor my profile or library, so I cannot install (let alone run) my games. The upper part of the window does show as normal, with the drop-down menus, but nothing happens when I click any option. I can't even see my list of friends or anything. I would attach a screenshot if I could, but it's just the Steam window without content, black and empty.
For this problem, I've seen some people that suggest adding the arguments -no-cef-sandbox or -no-dwrite on Steam's settings on POM, but that didn't help. Other people suggested running Steam under the Windows XP version, and that seemed to solve it for them, but Steam is no longer compatible with Windows XP, so I cannot even open it if I choose Windows XP. POM used Windows 7 by default, and changing it to other versions (Windows 8, or 10) didn't solve the problem either: Steam appeared black and empty again.
What might be causing this? And what can I do to solve it? It's probably worth-saying that the game I want to install is Age of Empires II HD Edition. Previously, I was playing it on my Mac using another wrapper, but suddenly Steam stopped working, and it began to appear black and empty, like now. I switched to POM hoping that it would be different, but strangely, I have the exact same problem. And I can run Steam out of POM, and play other games, compatible with Mac, without an issue.
I use a MacOS High Sierra, my version is 10.13.6. My graphic card is Intel HD Graphics 5000 1536 MB. And my PlayOnMac version is 4.3.4.
Thanks in advance!
