Possible Bug - Phantom Blocks - I Believe It's a Long-Known Problem

Oh don't be sorry thanks for the information. Yeah you are right about the bug being weird for different people. I think that's a first I've seen, someone having fast/strong ram and 32 gb at that, we're slightly different but mostly equal in that department. But I do have a HDD I can use to test, normally I'm on my m.2 or a regular SSD.

One common thing is the HDD, see if your friends are using HDD and if they are using an SSD/M.2 instead, please gather ram info from them. Unless you/they don't mind giving ram info, can't hurt! The last time I tested for it in a real game (not just testing random crap like in the repro i mentioned) I had 2 - 3 copies of the game running while running a membench in the background (among other stuff) to keep my ram as full as possible but didn't get any to stick. Pretty much had 100% cpu and ram utilization. But I'll make a new test using a HDD sometime soon.

2 interesting things to report.

First, out of 12 people who play on the Warhawk map, so far 5 have reported encountering the bug and the specs trend is predominantly HDD, though there was 1 person rocking an SSD.  RAM specs are all DDR4.  I'm still collecting specifics on brand, sticks, clocks, etc.  Will report those findings in full when everyone sends it in.

Second, I did an experiment and reinstalled my game to my M.2 (was originally on my HDD) and loaded into the map to see if the bug persisted and it hasn't.  Imposter marble blocks are visible as part of a POI's lod at long range but now they correctly derender at nearer distances.

Thinking that you're onto something with the hardware as a potential root cause, @Jugginator.

Ah beautiful thanks for doing that (not going to lie having the game on an ssd or m.2 is so much better lol). I was going to ask you if you had a faster storage medium to test it on and you went and did it, good thinking! I eagerly await the additional data, maybe this will lead to a solid reproduction

Almost like I do this kinda thing for a living 😜

RAM is Corsair Vengeance, 4 x 8GB DDR4 - 3200MHz base core clock.

Just curious, your CPU-Z shows your RAM is clocked at 2133MHz.

Which is pretty common if you don't set XMP in BIOS, and just leave the motherboard to set default values for everything.

Good observation.  I actually had to disable XMP to squeeze out better performance for Skyrim SE.  Apparently running almost 500 mods plus high-end ENBs causes quite the RAM drain 😵

Switching XMP off somehow stabilizes my system better for that setup.

I have been playing form a14 to the start of a19 and never had a bug that made me stop playing. I left for a few months after the start of a19, now Im back, and I cant play becaus of this bug. It happens to me in almost every POI

 
For those of you having issues with the distant POI meshes/ghost blocks, you might want to take a look at 19.5 experimental and see if any of the new optimizations and fixes there resolve your issue.

 
Never noticed that 19.5 was available until you posted that. How long was it out and was there a post saying it was?

Over 24 hours now, or roughly 19 hours before your post. There is the main announcement in the News and Announcements section. It was also broadcasted in the official Discord, Reddit, and Steam (both in your library, and the forum). It was probably announced in Facebook and Twitter as well, but I don't frequent those.

I went in news after and did see it and it said it was about 17 hours ago. I don't know why I didn't notice it as when I join forum first thing I do is click the unread content tab at top. And I have often seen Hated's post there announcing a new release. I just don't recall seeing it this time which is why I was caught by surprise.

There's a billboard near my house announcing it, and last night the commercial aired three freaking times, always right after the Liberty Insurance cell phone/rice commercial. Geez, TFP, enough already!

I personally haven't seen any ghost blocks for more than 2 weeks playing 19.5exp with CP47.

Seems like its fixed with 19.5 🤗

It's back... A21 

Is there a fix?

I have seen this too, even in A21 (though certainly not frequent). The only 'consistent' thing I have observed is that I have two systems (both using integrated graphics) and the one that has 8GB of RAM suffers from this issue more than the other one. Therefore I think it is a resource issue (lack of RAM or heavy swap file activity) and I suspect some textures cannot be loaded fast enough by the engine resulting in these 'default texture' blocks. A possible workaround is to move away from the area (or chunk) and reboot your system before returning.  7dtd likes RAM, so if you can add more (at least 16GB) that may also help. I have also had my laptop restart when the swap file grew too big to fit and it happened while playing 7dtd (which may indicate memory leaks which more RAM would compensate for). Good luck.

TLDR;

-reboot before playing

-reboot if anything starts to go 'funny'

-add RAM (at least 16GB)
