Godot freezes when the AssetLib tab is opened due to RichTextLabel bug

[gabe00122]

Godot version:

3.0-rc3

OS/device including version:

Windows 10 x64

When I open the AssetLib tab from inside an empty project Godot's main window freezes.

The following error is written to the console in a infinite loop:
ERROR: RichTextLabel::_process_line: Index line=0 out of size (l.offset_caches.size()=0)
At: scene\gui\rich_text_label.cpp:117

I'm haven't unfortunately been able to consistently reproduce this error, but it's happened to me twice on two separate windows machines. In both cases it was the first time I have run Godot on that machine. Both of the projects were empty.

I hope this was helpful.

Can't confirm on my machine (Arch Linux) using self-contained mode.

It doesn't freeze for me but it stutters. Don't know if it's caused by the connection poll or by the large amount of prints to the console.

EDIT: I misunderstood the original issue, I have nothing like that.

I have the same issue, but in a different situation.

Platform:
Windows 10 x64

Godot:
3.0 stable win64 (without mono)

Descrption:
I was editing a script. Pressed [Ctrl] [S] to save it, clicked accidently on 2D and only a few milliseconds later on 3D. The editor freezed. The console is repeating the same error message again and again. 2D and 3D are both highlighted.

Should I open a new issue for this? The console displays the exact same error message as this issue.

Can anyone reproduce this issue in the current master branch?

Can anyone reproduce this issue in the current master branch?

I remember encountering this months ago, both as described by the OP and @paul-dosenbrot .
I haven't seen it again for a while now.

Potentially related: On linux, with empty project and slow internet connection switching quickly between asset lib and another "tab" causes editor to freeze up. From what I can tell, it's when asset lib initially load until asset lib is completely loaded

[menip]

Can someone still reproduce the original issue?

[winston-yallow]

I was able to reproduce what menip mentioned. I was not able to reproduce the original issue on linux. I will try to reproduce the original issue on Windows 10 tomorrow, but I think I did not experience this in the last time (thought I do not use Godot on Windows often).

[winston-yallow]

I could not reproduce this on windows 10 anymore (even with very slow internet), seems to be fixed for me.

Godot Version: v3.2.dev.calinou.197b65f32

Seems like this is already solved them. We can reopen if someone can reproduce it.

@vnen The root cause of freezing is still unsolved. I'm having it too in latest 3.2.1.stable (in a different context though, but I don't think it matters). Please, check my comment in neighbouring issue #17815 (comment) , I may have specified correct direct cause of freezing there (but I have no idea, how the engine comes into a state when the issue fires)

@Calinou the user reports the error not to happen with the asset lib, but with the one click deploy/debug options (see the linked comment and follow-up).
Closing, let's discuss this in only once place: #17815 .
