Description Jan Alexander Steffens (heftig) 2010-02-06 15:57:51 UTC

Rotating or scaling the default cube (not the view) in blender causes a leak of gem objects. It accumulates multiple gigabytes within seconds, as reported by /sys/kernel/debug/dri/0/gem_objects. The system begins to thrash when RAM is full. The objects are released when blender is closed.

System:
Thinkpad X61t (GM965)
Arch Linux x86_64
xorg-server 1.7.4.901-1
KMS,UXA

Tested configurations:
Kernel 2.6.32.7-1
mesa 7.7-1
xf86-video-intel 2.9.1-1

and

Kernel 2.6.33-rc6-zen from git (2010-02-05)
xf86-video-intel from git (2010-02-06)
mesa from git (2010-02-06)

Leak happens using both.

Leaks:
blender 2.49a-1 from Arch
blender-2.49b-linux-glibc236-py26-x86_64
blender-2.40-linux-glibc2.3.2-x86_64-py24-static
blender-publisher-2.25-linux-glibc2.1.2-i386 (test caused the object bytes counter to overflow into negativity)

Does not leak:
blender-2.5-alpha0-linux-glibc27-x86_64
blender-2.49b-linux-glibc236-py26-x86_64 using accompanying software libGL

I can reproduce this, might be the same bug I reported in bug #24119.

Comment 2 Eric Anholt 2010-03-12 17:14:40 UTC

I think this is going to be the same root cause (I see only one type of leak occurring I think), so I'll mark this as a dup of the other.
