Graphical glitches and dark spots on Ubuntu 20.04

[canadajones]

Whenever I try to bring up a weapon, it shows up, but is covered in dancing dark spots. When I try to take a screenshot, the glitches do not show up on the resulting picture. However, they do show up on Discord screen share. I'm not at my home computer right now, but I will attach a picture when I get the chance. I also had an issue with distant trees turning black, but I've been unable to reproduce that one. I'm running on Ubuntu 20.04, with a Ryzen 3700x, an RX 5700 XT, 16 gigs of RAM and a terabyte SSD. I'm using the open source AMD driver. I've already tried -force-glcore and -force-vulkan. -force-vulkan simply crashes the game, while -force-glcore has the same aforementioned issues. Other games (mostly. some have poor Linux support, even if official.) do work well without significant issues.
Any pointers would be helpful.

I've seen this. There are many problems with the graphics in the linux version, and I suspect they're worsened using the amd video card. However, I found that running the windows version via proton worked extremely well. If you're playing from steam, it's as easy as right clicking on the game in the left hand pane, selecting "Settings", and then telling it to use a specific steam compatibility tool. I've found good results using the "Glorious Eggroll" build of Proton that's available on GitHub: https://github.com/GloriousEggroll/proton-ge-custom/ I'm using the latest 5.9 build, and he released a new 5.21 build a few days ago. Make sure you read the installation instructions; there are a few steps but if you follow the instructions it works very well.

Personally I think that the current linux version of the game is just straight up broken and has been for a long time; there are so many graphical problems that I personally find it impossible to play; have you experienced the flickering terrain problem?

Also, which mesa are you using? I'm using the latest oibaf ppa version:

It all seems to work fine, apart from the wielding models. I'm running the latest ones downloadable from AMD's website. I've also tried the hardware on a Windows install on an external HDD with no issues, so I'm fairly certain that my hardware is not at fault.
Running that same command spits out:

Also, I'm well aware that Proton is a thing, but I'd rather just add TLD to the growing list of Games I Will Play When I Set Up QEmu With PCIe Passthrough

Moving up to mesa version 21 might make a difference; you really should try the oibaf ppa for mesa. You can find it at: https://launchpad.net/~oibaf/+archive/ubuntu/graphics-drivers; it makes keeping it up to date on an ubuntu system completely automagic. 

I've found proton to be pretty excellent, allowing me to play things like the old bioshock games, the new Dooms, the tomb raider games, shadow of mordor, prey, the metro games, and so on, all with very good performance. YMMV I guess.
