I was just building and put this window into my house because it suited the style I wanted and then realised that they weren't transparent. I'm having the same issue.
I have all the updates so far. Windows. Game is in English. I don't have mods, but I do have CC, but nothing for this window. I know it used to work, so I agree that the patch that added more colours must have broken something. The other Mega windows seem to be okay.
I hope this thread is kept active and taken a closer look at, considering it had been out for a month at least with no recent activity until now, with no remediation. I’m wondering if this is part of the DX9 image update. But its odd that only this one window is affected.
