[Linux] Editor does not quit when pressing the X button

Linux

Aug 11, 2019

How to reproduce:
1. Create a new project
2. Enter Play mode
3. Exit Play mode
4. Press X to quit the Editor

Expected results: Editor shuts down
Actual results: Editor does not shut down, however it becomes unresponsive

Notes:
- It is not always reproducible, but it's mostly when a lot of work has been done on a beefy project (building, importing, loading)
- Up until 2020.1.0a8 this was always reproducible when the current platform was set to Android
- If this reproduces, the 'Unity' process disappears and the only way to quit the Editor is to kill the 'Main Thread' process
- When and if it crashes, similar stack traces to this are thrown:
#0 0x0055b7b70f3004 in DualThreadAllocator<DynamicHeapAllocator>::ValidateIntegrity(void const*) const
#1 0x0055b7b70e1702 in MemoryManager::Deallocate(void*, MemLabelId const&, char const*, int)
#2 0x0055b7b4e30c97 in dynamic_array<unsigned char, 0ul>::~dynamic_array()
#3 0x0055b7b7735895 in Texture2D::DestroyTexture()
#4 0x0055b7b766e838 in Cubemap::~Cubemap()

As of 12/5/2020 the bug doesn't exhibit crashing anymore

Resolution Note (fix version 2020.2):

Fixed in version 2020.2.0a8

Same problem still happens in Unity 2019.4.2f1 LTS after building to Android (Oculus Quest) using Ubuntu 20.04 LTS. Need to restart my computer to close it.

I'm also having this issue, tested with 2019.2.6, 2019.3.5, 2019.3.11, 2019.3.14. It also freezes when I try to re-enter play mode. Been using "pkill -9 PID" to work around it, but it's definitely slowing down my development. I'll be anxiously awaiting any fix or better workaround for this!

I have been using Unity 2019.3.12f1 on my Pop OS 20.04 for building Android Projects. Recently, this issue has been occurring most of the times. I make VR projects using Unity.

Unable to use the "kill" command to kill the process.

I have the same problem. Using Unity 2019.3.13 on Ubuntu 20.04. But I only have this issue when I do Android build.

Can confirm, happening on 2019.3.11f1 everytime I build to Android. If I'm not building to Android, application works as expected and closes normally.

Same here using Unity 2019.2.2f1 and 2019.2.21f1, some times it closes, and some others (when i work more time, do android builds, etc) it just wont close it, need to force close it directly.

wondered if it was a regression of this problem: https://forum.unity.com/threads/unity-wont-close.223446/

examining system monitor on Mint adb does apear to be running, but closing that does not seem to fix the problem with unity editor itself. after forcing unity editor to close using xkill, and closing unity hub, I've still got a lot of unity processes running.

Happening to me too with Unity 2020.1.0a24.3156 on Ubuntu 18.04 LTS. One workaround is using the command:

pkill -9 PID

PID can be found using the command top

Please fix...

Using 2019.3.0f6 I have the same issue, when I close the editor it just hangs and when I force kill it, I can't reopen it cause it says "project already open"

Stable reproduce on latest Unity Hub, latest Unity Editor and latest Ubuntu (KDE). Always hanging up on exit from Unity Editor.
