Recurring Game Breaking Issue playing on Linux, Constant Disconnects.

[aaronflash05]

OS: Arch Linux x86_64
CPU: AMD Ryzen 7 7800X3D (16) @ 5.053GHz
GPU: NVIDIA GeForce RTX 3060 Ti
Memory: 6683MiB / 31795MiB
Most recent match ID where this happened: 38177928

Bug: in a random match, the characters in the game will start rubber-banding until the point where all characters freeze and I can no longer move (over the course of a couple seconds, see attachment). After this It disconnects me or I do it myself (no difference in outcome) and I try to rejoin. Without fail the issue happens again at some random point in the same match and keeps happening until the match ends. Recently this bug has been happening almost every game I play and has made deadlock an unplayable experience for me, sadly. This bug is a deadlock exclusive bug, my computer can run every other game flawlessly (given a good protondb rating) deadlock is the only game where this issue occurs.

Throughout my time playtesting deadlock, I have had this issue pop up now and again, spontaneously and seemingly at random. I do not change the game between matches where is does and does not happen in any way. Throughout my 8 months of this issue occurring I have not found a permanent solution. I do not see anyone else have this issue when looking through the reddit, discord, or forums and in testing the fixes in related problems, none seem to work. The issue seems to be a connection issue of some kind because my game itself does not crash, I only get disconnected.

Things I tried:
verifying game files (does not work)
uninstalling and reinstalling deadlock (issue still occurs)
Installing deadlock on another drive (tested with ssd vs hard drive and there is no difference)
driver update (no change)
different proton versions (nothing)
trying proton GE (no change)
disabling/enabling steam recording (no change)
rejoining the match only lasts for a couple minutes before another disconnect. (see attachment)
disabling/ uninstalling mods (no effect)
game launch settings (various settings, none prevented this bug)
closing discord (no change)
restarting steam (no change)

I only use one keyboard layout

This bug makes this came completely unplayable for me and I have not found any fix that consistently works even temporarily. I got a recent time out with this last match which prompted me to make this bug report. It has become unbearable to play this game on linux so I hope this gets fixed or a solution is found.

I just started getting this issue as well. I've tried reinstalling the game and updating/restarting my PC.

You say you've had this issue for 8 months? I only just started experiencing it in my last two matches. I wonder if it's a server specific issue. Or ISP because I did recently move Not ISP because I don't get the issue at all on Windows. My connection seems pretty reliable, 1Gib, ~10 ping. Don't have connection issues with any other game.

I played 4 matches today. The first two were flawless, the the last two I was getting constant disconnects.

OS: Arch Linux x86_64
Host: X570 AORUS ELITE WIFI -CF
Kernel: 6.16.3-arch1-1
DE: GNOME 48.4
CPU: AMD Ryzen 7 5800X3D (16) @ 4.552G
GPU: NVIDIA GeForce RTX 3090

I hope this gets resolved, but if it's not occurring on Ubuntu then they might not even look into it since Arch is not officially supported by Proton. Maybe they'll release a native Linux version

Also seeing this in Arch. Hardwired connection. Last couple weeks.

OS/Kernel: Arch - 6.16.4-arch1-1
DE: Hyprland
CPU: Ryzen 5900X
GPU: NVIDIA GeForce RTX 5090 (also replicated on an A6000)

Captured wireshark logs for any interested devs.

Same issue here.

OS/Kernel: Arch - 6.16.4-arch1-1
DE: KDE Plasma
CPU: Ryzen 7900X
GPU: NVIDIA GeForce GTX 1070

Hardwired connection. Also nothing else disconnects and I was pinging steam servers while I was dcing and wasn't noticing anything

Hi! I think I'm having a similar issue.

[Issue description: ]
I can't play through a match without beginning to experience severe rubber-banding/teleporting and general desync.
Game will run smoothly at ~140-160 fps with less than 30 ping and ~ 3 ms net jitter for a large portion of the match, then suddenly the net jitter raises to ~ 130 ms and becomes unplayable.

It is of note that this issue does not occur on other games on this device.

[Steps to reproduce: ]
Launch game -> load into match -> play for 10 to 15 minutes.

[Resolution: ]
Exiting game and relaunching solves the issue temporarily.

[Hardware and OS information: ]
OS: Debian GNU/Linux 13 (trixie)
KERNEL: 6.12.43+deb13-amd64
CPU: AMD Ryzen 7 7700X 8-Core
GPU: AMD Radeon (radeonsi, raphael_mendocino, LLVM 19.1.7, DRM 3.61, 6.12.43+deb13-amd64)
(I am using a 7900XTX gpu, this is just what steam reports about my system from a native installation of the binary)
GPU DRIVER: 4.6 Mesa 25.0.7-2RAM: 31 GB

[Additional Info:]
I don't believe that this is actually a network issue. I am using a cat6 Ethernet cable, connected to a 1Gb optical fiber line. Network is extremely stable for other applications and games. ISP is AT&T.
The game actually runs very well when this issue is not happening, and it seems to happen due to *something* occurring during a match. Maybe a map update or something, but I haven't narrowed down a specific time-frame.
Interestingly, though the game visually appears to be lagging with rubber-banding and such, it doesn't "feel" like it. I.E. shots connect based on personal prediction, movement is smooth... It's like it's just visual tearing, but the game is convinced that it is Net Jitter, as that's the warning that pops up on screen.
