Public bug reported:
When playing Unity3D games using Steam, if the game window is unfocused,
the game may freeze. If there were any sound effect being played, they
continue until they end playing and then they stop.
Steps to reproduce:
1) Open Unity3D game on Steam;
2) Make the window lose focus somehow (move a Firefox window on top of the game
screen, lock the screen, change monitor settings);
3) Notice how the game freezes.
When closing the game, it will ask if you want to force close it or
wait, as the game is now frozen.
So far, this was observed with Demonic Mahjong, PHOTON CUBE and Prime of
Flames. It can be reproduced using the Prime of Flames Demo on Steam.
The computer is an IdeaPad Gaming 3 15ACH6 with a NVIDIA GTX 1650,
nvidia-smi says driver is 580.82.07, nvidia-driver-580-open package was
installed. I'm using Xubuntu Resolute.
