@VAHNeunzehnsechundsiebzig.3618 But anyway: Mesa: 19.1.2-224.1 And now the correct adressed one ;) : @ArmoredVehicle.2849 Yes, tried that too. "ulimit -Hn" and "ulimit -Sn" both print '1048576'. And as I said, your legacy packages works perfect, no crashes at all. But the vulkan package crashes every few minutes, no matter which map. So the chances are high, that something in the vulkan package triggers the crashes for me. Thanks for your help anyway and your great packages.
