Errors with new Proton versions without --no-bwrap

[SeongGino]

Describe the bug Title; New Proton versions (GE-Proton7-14, Current Experimental) will be unable to access the main shell window without --no-bwrap appended.

Instead, when invoked normally:

pressure-vessel-wrap[73512]: W: Disabling gtk3-nocsd LD_PRELOAD: it is known to cause crashes.
pressure-vessel-wrap[73512]: W: Binding directories that are located under "/usr/" is not supported!

To Reproduce Steps to reproduce the behavior:

1. Set game's Forced Steam Play compatibility tool to Proton Experimental or Proton GE 7-14
2. Run command protontricks appid --gui/select a prefix using the appid gui.
3. Observe the errors as winetricks exits early.
4. Run the same command with --no-bwrap appended before appid.
5. Observe winetricks launching properly.

Expected behavior The winetricks shell window should appear in normal use without additional flags.

System

• Distro: Arch Linux
• Protontricks installation method: chaotic-aur repository, then manual AUR build for case of issue.
• Protontricks version: 1.8.0 / 1.8.1
• Steam version: Beta

Additional context

Issue does not seem to apply to 1.7.0 (the version available in protontricks PKGBUILD), and behaves as expected. Issue applies to 1.8.0, with the only difference being a lack of pressure-vessel-wrap and wineserver-keepalive errors, but does maintain the bad wine version error and empty AppData string message before exiting early.

[Matoking]

From what I can gather so far, you might have a Steam library configured under /usr which Steam Runtime is complaining about and is not supported. If you can, you could try removing the corresponding Steam library temporarily and check if that fixes the issue.

That said, the real issue might be something else: if so, try running the command again with -v flag (eg. protontricks -v <appid> --gui) for additional log messages and post them here. You can upload it under gist.github.com if it's very long.

I can say for certain that no library of mine is using /usr; the only subdirs Steam is using for games is under /mnt (a different drive) and /home (the running system's drive). The error is also the same regardless of it being a used prefix or fresh with no verbs added, if that helps any.

I wasn't able to reproduce the issue on Arch using either the newest Proton Experimental or by placing the newest GE-Proton version under /usr/share/steam/compatibilitytools.d; the latter works without problems despite the warning.

Since you didn't have any issues on 1.7.0, it could be related to pressure-vessel-launch that is used starting with 1.8.0.

Could you try starting a shell with the command protontricks -v -c bash 35140 and testing the following commands:

$ "$PROTON_DIST_PATH/bin/wine" --version
wine-7.0 (Staging)
$ wine --version
protontricks - wine 63821: Checking for running wineserver instance
protontricks - wine 63821: Found running wineserver instance with PID 63166
protontricks - wine 63821: Copying env var from running wineserver: WINEESYNC=1
protontricks - wine 63821: Copying env var from running wineserver: WINEFSYNC=1
protontricks - wine 63821: Starting Wine process using 'pressure-vessel-launch'
protontricks - wine 64070: Starting Wine process inside the container
protontricks - wine 64070: Appending to LD_LIBRARY_PATH: /usr/share/steam/compatibilitytools.d/GE-Proton7-14/files/lib:/usr/share/steam/compatibilitytools.d/GE-Proton7-14/files/lib64:
wine-7.0 (Staging)

The first command runs the Wine executable directly without using pressure-vessel-launch, while the second command uses it. In my case, both commands work correctly, but in your case the second command will likely fail.

---

One another issue I can think of is that your /tmp (which Protontricks uses to store a socket and some other temporary files) might have different settings that are causing problems. We could test this by using a different location for temporary files and checking if that fixes the issue:

mkdir ~/tmp
TMPDIR=~/tmp protontricks -v 35140 --gui

[SeongGino]

To part 1: it's exactly what you said would happen.

$ "$PROTON_DIST_PATH/bin/wine" --version
wine-7.0 (Staging)
$ wine --version
protontricks - wine 143650: Checking for running wineserver instance
protontricks - wine 143650: Setting default env: WINEFSYNC=1
protontricks - wine 143650: Setting default env: WINEESYNC=1
protontricks - wine 143650: Starting Wine process using 'pressure-vessel-launch'
Segmentation fault (core dumped)

To part 2: No change from before, so I'll leave the output attached. output.txt

[Matoking]

OK, there's a chance that the Soldier runtime + launcher isn't playing nicely with your system. To check this, we can run the commands Protontricks uses manually and check what happens. To do this, open your Steam library and find "Steam Linux Runtime - Soldier" (you'll have to check "Tools" under the options to make it visible), right-click it and select -> Properties -> Local Files -> Browse...

Open two terminals in the directory, and run this command in the first terminal and keep it running:

$ ./run --share-pid --launcher --filesystem /boot --filesystem /etc --filesystem /home --filesystem /mnt --filesystem /opt --filesystem /root --filesystem /sbin --filesystem /srv --filesystem /tmp --filesystem /run/media --filesystem /usr/share/steam/compatibilitytools.d/proton-ge-custom -- --socket="$HOME/test.socket"

After that, run the following command in the second terminal:

$ ./pressure-vessel/bin/pressure-vessel-launch --share-pids --socket="$HOME/test.socket" --pass-env-matching="*" -- vkcube

The latter command should display a window with a spinning cube or crash with a similar error as when you're using Protontricks. If it crashes, does either command print a more verbose error?

---

Another possible cause if the previous test didn't reveal anything, is testing --no-bwrap --background-wineserver like so:

$ protontricks -v --no-bwrap --background-wineserver 35140 --gui

Background wineserver is only enabled by default when bwrap is used, so turning off bwrap might appear to be the reason for the crash even if the background wineserver is actually at fault here.

[SeongGino]

The second command simply prints Segmentation fault (core dumped). All I get from the first terminal is:

pressure-vessel-wrap[1359185]: W: Disabling gtk3-nocsd LD_PRELOAD: it is known to cause crashes.
pressure-vessel-wrap[1359185]: W: Binding directories that are located under "/usr/" is not supported!
socket=/home/seong/test.socket
dbus_address=unix:path=/home/seong/test.socket

Apologies for my ignorance, but am I supposed to be seeing something else here that's more helpful?

The latter command (despite the winetricks update notice, ugh) works though.

OK, it appears that Steam Runtime's pressure-vessel-launcher isn't working correctly for some reason.

Protontricks uses it to launch individual Wine processes more quickly: in 1.7.0 and older, every time a Wine command was called Protontricks would use Steam Runtime to launch the command inside a new sandbox, which has a small startup time which starts to add up once lots of Wine commands are executed.

Starting with 1.8.0, Protontricks instead launches a pressure-vessel-launcher process that creates a single sandbox and listens for any commands to run inside the sandbox. Protontricks uses this method to launch Wine commands without the startup time cost, greatly improving performance with Winetricks and other applications that run a lot of short Wine commands.

The fact the Segmentation fault (core dumped) error happens even when we test Steam Runtime in isolation seems to indicate it's an issue with Steam Runtime, not Protontricks. You could try verifying the local files for "Steam Linux Runtime - Soldier" and check if that solves the issue, but I'm a bit doubtful that'll work. In that case, opening a new issue for Steam Runtime seems to be the best option.

Indeed, I tried verifying files, but Steam doesn't find anything wrong with the runtime. Interesting! Especially since you say you couldn't reproduce it on your system. Unfortunately, I simply don't have the disk space to try a second install and piece out what wayward package could be somehow causing issue with this, but there isn't anything particularly unusual for my Arch install that I could think of which might be an issue...

hello, currently experiencing the same issue on Manjaro Cinnamon on X. any version above 7.14 of proton give the error. same step's to reproduce as SeongGino. and as mentioned --no-bwrap even when using --gui makes it work.

installation method: built from source (AUR) version: 1.8.1 proton GE version tested 7.14 7.15 7.16 7.17 7.18 7.19 7.20

Strange; since my last comment I've reinstalled Endeavour on my system (for wholly logistical reasons). And I think I've gotten back most of my old packages/AUR imports, but protontricks works fine now. So I can't seem to be able to reproduce the initial issue. (It's the same exact piece of install media too, but both installs are/were online; also the same exact ~/.steam instance that I'd transferred from/back to my home, and tested with prefixes that also were transferred whole from the old install.)

Could Manjaro be the issue? Maybe reinstalling the base system could fix it? That's the only way I was able to get expected behavior from my end, anyways.
