3D Acceleration Should [Try Harder To?] Free Textures On Application Exit -> Fixed in SVN

Reported by: fullreset Assigned to:
Priority: minor Component: 3D support
Version: VirtualBox 3.0.8 Keywords: texture memory
Cc: Guest type: Linux
Host type: Mac OS X

Description

The Problem:

- Tracking texture IDs returned by OpenGL in the Guest OS across several application launches suggests that under abnormal termination (eg signals, incl SIGINT) makes no attempt to free textures.

- Furthermore, many applications are 'sloppy' about freeing textures, assuming that the OS/libs will do so when the program ends (regardless of cause.)

Suggested Solution:

- Texture state should be tracked throughout the life of the application, and when/where possible textures should be 'collected'.

Notes:

Only tested with Linux Guest under Mac OSX Host; this problem may exist elsewhere.
