Multiple GUI instances of Vital open causes deadlock if the host also uses OpenGL on Linux with NVidia

[jcelerier]

Hello,
as the title says:

• My host (https://ossia.io) uses OpenGL for rendering under Linux (in the main thread)
• I can run one instance of vital without issues (but maybe I've just been lucky)
• However, if I open a second vital UI, I get a deadlock of the whole software very quickly:

main thread:

vital:

Thus my question, as this smells a bit like a driver issue which is not directly addressable: is it possible in some way to have a way to make Vital's UI driven in the main thread instead to avoid that case ?
