Looks like an issue with your openGL system setup issue on your system:

The first crash report is caused in /usr/lib/x86_64-linux-gnu/dri/amdgpu_dri.so (distro provided), while the second one references amdgpu-pro in a different location:

```

#2 0x00007fff6822b958 in AGER_Reloc2ICD () at /opt/amdgpu-pro/lib/x86_64-linux-gnu/libGL.so.1
#3 0x00007fff6825ca39 in glXMakeCurrentReadSGI () at /opt/amdgpu-pro/lib/x86_64-linux-gnu/libGL.so.1
```

There is a related know issue: Crashes when one opens multiple plugin windows using nvidia graphics cards and the free-software nouveau driver. That driver limits every app to have at one most openGL window.
The solution there is to use the nvidia binary driver (or only use one plugin UI at a time).

I'm not sure if this is related to your issue but it may be something to investigate.

But my graphics card is an AMD with AMD drivers, not nvidia. And only happens sometimes...

Just now crashed without loading any plugin, only a new and fresh project...

This is why I said it is a **related** issue.

Still`glXMakeCurrent` is also where things go wrong with nouveau as soon as two different windows request the GL context. They optimized for single window games (and never supported multi-window applications).
Maybe AMD followed them..?

PS. dump3.txt looks like a complete unrelated issue. Some Region Drag/Drop?
