Describe the bug:

I've noticed that closing windows (on the OS level), which contain a Table widget sometimes causes the entire app to crash.
I managed to trigger it a few times with the sample code, but it seems to be kinda random on when it hits.

Traceback:

fatal error: unexpected signal during runtime execution

Can you please test with v2.0.1 I think this was a duplicate of #1604

That fyne version already had the fix for #1604, but I ran it again with 2.0.1 and sure enough, it crashed again.

I actually ran it a few times and got crashes not only in SwapBuffers() but also in Clear().

I think this is a Linux specific thing, because I can't reproduce this under Windows.

Also now I'm pretty sure that the table has nothing to do with the crash, so I'll change the name of this issue.

Thanks for the info, we'll get some Linux testing on

It also occurs on MacOS, so I don't think it is Linux specific. Unfortunately (or fortunately?), it is really hard to reproduce it 😞

I see this crash as well on Mac M1. First I experience with my app and then also reproduced with fine example app.
I try with fine:
fyne.io/fyne/v2 v2.0.3

go version go1.16.4 darwin/arm64

For me the crash reproducible when I resizing the window. A few attempts of fast resizing will produce this stack (fine example app):

$ ./examples

I think this is two different issues. The Table thread issue is likely resolved as we changed the threading model for render on all except M1. The M1 resize issue is tracked elsewhere.
