Memory leaks in Xorg
Hi, Everyone.
I'm working software developer.
I'm having a problem right now.
Continuing to decode H.264 using ffmeg and libva causes a memory leak in Xorg.
This is especially likely to occur when the resolution is scaled (both UP and
Down).
The settings of 20-intel.conf are as follows.
[20-intel.conf]
------------------------------------------
Section "Device"
Identifier "Card0"
Driver "intel"
BusID "PCI:0:2:0"
Option "AccelMethod" "sna"
Option "SwapbuffersWait" "False"
Option "TearFree" "True"
EndSection
------------------------------------------
If you do not set TearFree, memory leaks will not occur, but tearing will occur.
It does not occur on Ubuntu 16.04 with the same settings.
Is there a way to eliminate the memory leak and prevent screen tearing?
