I did investigate further and it seems to be related to SSL rather than to nvidia drivers: ltrace fgfs | & grep https ... _Znwm(1104, 0, 92, 0x7ffe09cb9a00terrasync scenery provider of the day is 'https://dream.t3r.de/fgscenery' memcpy(0x5599abed0f60, "effect", 6sync of https://dream.t3r.de/fgscenery/Models started, queue size is 26 It crashes when trying to download via https. Surprisingly the option --disable-terrasync has no effect, it still tries to download from terrasync scenery provider and crashes.
Without any change to local software it started to work again about 2 days ago. Probably something has been changed on the server it was connecting to via SSL.
