Segmentation violation when drawing figure in MATLAB2012

Hello fellow Matlabers,

We need to use Matlab2012b because a toolbox we use is only supported in that version. Unfortunately Matlab crashes as soon as we start to draw anything in 'figure'. The attached file shows a crash dump that we got after:

> figure
> plot(1.2, 1.3)

The issue can be reproduced on Centos7 and Ubuntu 20.04 (all with the latest patches) and has been seen on multiple computers.

We did not see the issue, when we use Display-Forwarding though.

Everything we tried so far did only lead to the same error.

We tried to contact Mathworks about this issue, but it seems that Mathworks does not support these old versions anymore.

Did anybody enounter this as well and has a solutiion?

Thank you very much in advance.
