unityhub, Attempt to free invalid pointer

[soupglasses]

Describe the bug

A clear and concise description of what the bug is.

Running directly through unityhub

``` (Unity:11807): Gtk-CRITICAL **: 16:29:53.599: gtk_container_foreach: assertion 'GTK_IS_CONTAINER (container)' failed ``` ``` Unable to load player prefs ``` ``` ../../third_party/tcmalloc/chromium/src/tcmalloc.cc:289] Attempt to free invalid pointer 0x564dc9d7c5a0 ```

Running with steam-run:

Running unity with steam-run does not help.

Another bug, might be the actual issue.

May be related from my radeon card?

[soupglasses]

Looks very similar as #271483, as this worked a month ago, but recently has stopped working completely for me.

[soupglasses]

Yup. Running LD_PRELOAD=/nix/store/hbqq0way8sy1z4zd1h5nvmmv1v2cxfp1-gperftools-2.10/lib/libtcmalloc_minimal.so:$LD_PRELOAD unityhub fixes the issue.

[huantianad]

Can we fix the issue by adding the package to the FHS env? Is that something we should do?

[soupglasses]

Hit a new fun errors when attempting to do some work. Unsure if this is a one off or not.

Can we fix the issue by adding the package to the FHS env? Is that something we should do?

I tried adding it as a extraLibs override, but it seemed to have no effect. Forcing it at the terminal helped.

[soupglasses]

Aside, but there seems to also some missing fonts, im guessing Arial or something similar issn't getting substituted. Unsure how to help that besides chucking the MS fonts at this.

[huantianad]

Supporting Unity 2019 in general is always tricky, as I believe by this point it is EOL, and thus lacks a lot of the necessary changes and updates included in newer Unity versions to be more compatible with modern Linux systems, at least in my limited experience.

It seems that in order to fix the invalid pointer issue, we do need to add the mentioned package specifically to LD_PRELOAD. This can be done in the main unityhub package, but I'm not sure if this can cause any other issues with newer versions. I haven't seen any alternative solutions though, but perhaps there are?

Looking at your crash log, nothing stands out to me immediately. Are you attempting to open an existing project? If so, could you try with a blank project, just to check if this is a project specific issue.

I personally haven't hit anything with missing fonts, but I don't think it's super feasible to include the MS fonts package alongside unityhub automatically. This could be another thing fixed in newer unity versions too perhaps

[soupglasses]

The error seemed to only happen once or maybe twice, restarting Unity got past the crash.

The font rendering issue was specifically with VRChat's upload stage, which runs as a game inside the Unity player. All UI elements in Unity seem fine, besides some black windows that pop up occasionally, not sure what they are, but they never stopped me using Unity.

[huantianad]

Ok, we can ignore that crash for now.

If the font rendering issue is in the player, I feel like that might be something that needs to be fixed in the game itself.

I'm not sure if we should edit the unityhub package to include the workaround, #271483 still hasn't been closed with a fix to the steam derivation, so perhaps we should continue to wait to see how they resolve this.
