Notou uma mudança no meu equipamento 16.04 (64 bit) rodando Unity . Examinou syslog e xorg.0.log e observou um fluxo quase contínuo de erros sendo registrados.
Saída do arquivo de log de amostra ... Para syslog :

Para xorg.0.log :

Configuração:
Processor: Intel® Core™ i5-2400 CPU @ 3.10GHz × 4
Graphics card: AMD Radeon (TM) RX 460 Graphics
Driver: amdgpu-pro-16.50-362463
Eu desinstalei o driver amdgpu-pro com sucesso e reverti para os drivers padrão (aceleração gráfica limitada ou não) e syslog / Os erros xorg.0.log foram interrompidos. Eu instalei os drivers AMDGPU-PRO-16.50-362463 mais recentes e os erros de log retornaram .
Gostaria de ver se há alguém lá fora com uma solução (além de mudar a arquitetura da placa gráfica).
