walking through hallways to travel through "worlds" crashes on linux #1020

Open charlie-sans opened 5 months ago

charlie-sans commented 5 months ago

built from source the latest clone as of 13/6/24 the overte-builder and github repo.

when trying to visit any world which does a fancy travel to another world type thing, the game will play the travel sound and then hang for a few secconds before force closing the game.

on fedora 40 so heres my neofetch if needed image

I cannot reproduce this on version 2024.06.1 or on current master (https://github.com/overte-org/overte/commit/5507ac363234a9ee2bc5827290948ef156794c70). Could you post a backtrace by running Overte with gdb your/path/interface and then typing bt after it crashed? You could also try if you can reproduce it on the latest release AppImage. (Here is one with debug information for GDB: https://public.overte.org/build/overte/release/2024.06.1/Overte-2024.06.1-debug-x86_64.AppImage) Also, could you tell us an exact portal that causes the issue for you? If you stand at the portal, you can go to Navigate (in the top menu bar) and press Copy address to clipboard, that way you can paste the location in here.

charlie-sans commented 5 months ago

so i have the portal that caused the issue hifi://virz-junction/-9024.46,-8952.65,-9023.22/0,0.707299,0,0.706914

i can't seem to replicate the issue at all, ill try with the app image

charlie-sans commented 5 months ago

so attempting to use the app image with gdb might be doing things wrong lol i get

@charlie-sans after that (No debugging symbols found message, it should show a (gdb) prompt. You just type run in there (I forgot to mention that).

JulianGro commented 5 months ago

If this issue only rarely happens, it might be a deadlock related to changing worlds, not specifically teleporting.

AleziaKurdis commented 5 months ago

It happens very often. It also happen from the Places app too. This is really annoying... up to 4 - 5 time each night. and sometime when it work, some script just don't load at destination, which is also problematic. we often reappears at coordinates 0,0,0 when we restart interface after such kind of crash.

ksuprynowicz commented 5 months ago

Is happening this on the newest release?

JulianGro commented 5 months ago

I assume we are all talking about the same deadlock(s?), so yes. The latest release also sometimes has issues. Seems like there are still more issues when changing worlds. In my case it feels like it is more likely with worlds that have a lot of stuff in them, like the Hub.

AleziaKurdis commented 5 months ago

For navigation to an other domain, I would say it started with RC1 For script loading issue it started with V8, it get better with RC1 but there is still some random script that are sometime not loading.

ksuprynowicz commented 5 months ago

I found the reason why this happens :)

vtable for QQmlPrivate::QQmlElement<QQuickItem> 0x00007ffff3b666a8
TabletButtonListModel::removeButton TabletScriptingInterface.cpp:112
TabletProxy::removeButton TabletScriptingInterface.cpp:926
Application::notify Application.cpp:4292
main main.cpp:776

We are looking into possible solutions now.

ksuprynowicz commented 5 months ago

This could be another possible cause, but might be a bit more difficult to fix: https://github.com/overte-org/overte/issues/1034

ksuprynowicz commented 5 months ago

Also this one: https://github.com/overte-org/overte/issues/1035

Armored-Dragon commented 2 weeks ago

This is still an issue as of the 2024.10.2-rc2 release. My uneducated guess based off of this comment is that the application tries to remove apps that were installed by the place you visit, and fails. If this is true, then as long as you don't spam loading into worlds that add stuff to your toolbar, you will be better off.
