My apologies for posting to the wrong section - I wasn't really looking for "support" rather than just a discussion in general as we take a quick romp down memory lane, but anyhow, details:
I'm running the linux version on Slackware 14.2, current kernel is 4.4.157.
Video card - current card is nVidia 1060, but with my old 660 it did this also. Driver is nVidia proprietary. No specific version, I've seen this for a long time with different driver versions.
32 bit and 64 bit client both do this - the 64 bit client is commented out in 7DaysToDie.sh, but I just run it manually from the console.
Memory - currently 24GB.
Video settings - doesn't matter, I've maxed out eye candy, minimized it, and tried everything between, I haven't found a video setting that effects this.
A13.8. (b7).
Back when 13.8 was the current version, I noticed this, but did not pay attention. In newer versions you can see through windows, I figured it was something that was just fixed in later versions. IIRC, this never worked - are you sure windows are see through 13.8? It works fine in later versions.
So, I craft a "Wood Window". Actually I craft a lot of them because when I move into an abandoned house, I like to replace the broken windows. Place window in window frame or wherever you want to put it. You get a nice windows frame with a black non-see through pane. I'll see if I can post a pic.

The window is the upper right black pane, I just now crafted it and placed it there.
