Just witnessed a problem with driver 440.44 when trying to play Shadow of Mordor’s Linux Vulkan beta (Feral Interactive). The game won’t start. I see the game’s loading ring on a black background, but at some point it freezes my whole system. I have to ctrl+alt+f1 & ctrl+alt+del to reset my computer. I reverted to driver 435.21 and it solves the issue.
