Bug Reports

Summary: Client freezes when using String Loading under certain conditions. Phenomenon: When downloading a binary file using StringLoading, the VRChat client freezes for about 1 second immediately after the download (just before OnStringLoadSuccess is called). The size of the binary file at this time is 44MB. The freeze time is proportional to the file size. Comparison: Unlike the binary file, the freeze does not occur when a text file is downloaded. The size of the text file is 59 MB. Terminology explained here: Binary file: A file whose characters cannot be decoded as UTF8. Text file: A file whose characters can be decoded as UTF8. Test worlds: You can test the failure in the following worlds. The worlds have two buttons to download binary files and text files, and an image of the U# code (also attached this post). (The left button does not cause the freeze. The right button does.) https://vrchat.com/home/world/wrld_491e05ae-11f3-4173-b2bd-ba00f3e9ed47 Backgrounds: The gimmick I create often handle about 50MB of data. The gimmick downloads the data as text files currently. Binary data is processed by converting it to Base64 strings. However, if the binary data could be handled as is, it would be very useful because it would reduce the amount of space and remove Base64 processing. Therefore, I tried downloading the binary file and changing it to read in ResultBytes, but this caused a freeze. This freeze is not acceptable for world users, and until it is fixed, I cannot handle binary data processing directly. Suggested fix: My guess is that the problem is occurring because stringify the binary file is running just before OnStringLoadSuccess is called. Therefore, I propose two ways to solve this problem. Do not stringify the binary data (Encoding.UTF8.GetString()) until calling result.Result. In other words, if only result.ResultBytes is called, the stringify is not performed. Do the stringing process in a new thread, not in the main thread of VRChat.

By setting the playback speed of VRC Unity video player to 0-1x speed, players who join later may crash. This means that there is a possibility that no one will be able to join the world that has this setting unintentionally. Reproduction steps Player sets video player playback speed to 0-1 When a late joiner joins, there is a probability that VRChat will crash. Further investigation is required to determine the exact conditions that cause the bug. Symptoms of crashes include crashing after a certain amount of time without sound being played, crashing when moving to another world, and crashing when opening the menu and touching an icon. This is probably triggered by the SE playback event occurring. If you cause this bug, a large amount of logs such as "Warning - AudioSampleProvider buffer overflow. 1024 sample frames discarded." or "Warning - AudioSampleProvider buffer overflow. 2048 sample frames discarded." are output to the Debug log. This bug occurs in video players commonly used in Japan. What these players have in common is that they use animation to change the "VRC Unity Video Player" parameter "Video Player.Playback Speed" to change the playback speed.

When sending avatar parameters rapidly, there is a chance that upon avatar switch, there will remain parameters from the old avatar in all future returned OSCQuery JSON until the game is restarted. So far, I've been able to filter these erroneous parameters out by just ensuring all parameters have a type tag (which the ghost parameters consistently lack). Attached is a preview of one of these occurrences. The avatar loaded in the attached image doesn't even contain this parameter anywhere.

OscQuery requires each node is capable of responding HTTP requests pertaining to the OSC methods that it's able to read/write to/from. VRChat should then only send to these addresses due to it now knowing what addresses the node needs. Despite this, VRChat sends all values to the client over OSC anyway. This has been an issue since OSCQuery's launch. For example, I only need to receive information about avatar changes (/avatar/change), and my HTTP server responds with that single address as a read/write string value, yet it sends all values anyway, and I need to parse every single one of them to find the correct one. Fixing this would improve performance both on VRChat's side not having to encode all that unused OSC data, and on the app's side only having to decode the relevant data to find the data it actually needs.

Be not in the same instance with the profile you check. Open Profile in MM It shows the account as "User" while it's actually a "New User". Joining the person adjusts it to "New User" rank. Leaving the instance causes it to show "User" again. From my observation everyone gets shown as 1 rank higher (friends and non friends)

When losing connection to a world with a queue, such as "VRChat is not responding" or "Your connection to VRChat timed out", the game will hard crash when trying to rejoin the world. The game attempts to reconnect, and when it fails, it tries to send you to your home world, upon which, the game crashes before loading your home world. This happened to me and one of my friends, so it should be reproduce-able. It happens on both the main branch and beta.

Open QM click Worlds (opens Worlds in MM) check screenshot Sometimes it shows no world. Sometimes it shows some worlds. It's definitly one of the more rare bugs. Happened about 5 times in the last 2-3 weeks. Reopening Menu or changing Category on the left fixes it temporarily.

I don't even own a oculus, i have an index, but in Unity there seems to be something wrong in the "packages/com.vrchat.base/integrations/oculusspatializer/audiopluginoculusspatializer.bundle" It's doing an infinite import loop. I would appreciate if this would be looked into.

Whenever I join on VRchat I get this bug often, where my avatar disappears via mirror. I tried to delete and redownload the game, I tried to switch Avis and reload worlds but it doesn’t fix it.

When launching the same account more than once using the Quick Launcher (using a local world), all PhysBones and Contacts do not work. However, when using two separate accounts, the functionality of PhysBones and Contacts works
