ffmpeg x11 screen recording crash

I have a single line script to record screencasts on my laptop using ffmpeg. It was working fine last month, but today I updated the packages and each time I try to record the screen, the X server crashes into tty.

Here's the ffmpeg script:

#!/bin/sh
ffmpeg -video_size 1920x1080 -framerate 30 -f x11grab -i :0.0 -loglevel error -preset ultrafast -vcodec libx264 -qp 0 -pix_fmt yuv420p -f mp4 ./test.mp4


Here is what Xorg.0.log records:

Some logs that may be useful (ffmpeg version, x11 version...)

Code: 
$ uname -a

I tried to record some ffmpeg logs but Xorg crashes before the log file can get anything.

I appreciate any idea on how to solve this issue. It's really strange, I think that most probably I'm missing something that has changed between updates, and maybe there are not-met dependencies or another flow to grab the X11 screen from ffmpeg but I can't seem to find it.
 
I haven't recorded screen for awhile, but remember that I had to rebuild multimedia/ffmpeg with adjusted options every time after binary packages were updated. I'm using the same script for recording.

[update] Have you tried recording a smaller portion of the screen?
 
I have tried to record a smaller portion too with no luck. I've also been reading some of the other forum posts about screen recording with ffmpeg, and I've checked that multimedia/ffmpeg has the "XCB" option on. Maybe there are other options that have been turned off and cause the issue, that idk for now.

I'm trying your script and multimedia/peek and I'll report if anything changes.
 
You may try disabling OPTIMIZED_CFLAGS.
Although I'm not sure whether enabling XVIDEO matters, it may help too.
