Description Matthew Turnbull 2016-12-30 23:10:56 UTC
Upgrading x11-drivers/nvidia-drivers from 370.* to 375.* causes xscreensaver's glmatrix (run via cinnamon-screensaver) to hang on exit and consume 100% cpu.



$ ps -ef | grep gl
sparky    2292     1 98 15:32 tty1     00:13:43 /usr/lib64/misc/xscreensaver/glmatrix -root -delay 54867 -density 50 -speed 3.5956 -no-rotate -window-id 41943043
$ cat /proc/2292/stack 
[<ffffffffb18012bc>] exit_to_usermode_loop+0x3c/0x70
[<ffffffffb18013da>] prepare_exit_to_usermode+0x2a/0x30
[<ffffffffb1c6779b>] retint_user+0x8/0x10
[<ffffffffffffffff>] 0xffffffffffffffff



Repeatedly locking and unlocking the screen causes these hung processes to accumulate until manually killed.

I'm speculating that this is a bug in the nvidia drivers, however, I can only reproduce this wonky behavior with xscreensaver.

Looks a lot like bug #478074.
