Not related to Globulation 2 but rather your XGL drivers.

No issues under AIGLX, XGL source of problem.

Someone please set status to closed.

Hello,

I've checked texture allocation code. Glob2 does not leaks textures but rely on OpenGL driver's ability to implement cache policy and offload unused textures from GPU.

Following your report, it seems to me that xgl cache policy is a simple fifo instead of a real cache. I suggest you report this issue to xgl alonside with this description.

Thanks, have a nice day,

Steph

Ubuntu Dapper v 6.06 running xgl with Beryl and Emerald off of
deb http://www.beerorkid.com/compiz/ dapper main aiglx
deb http://media.blutkind.org/xgl/ dapper main aiglx

Pentium 4 2.99 Ghz with SMP
1024 MB PC3200 SDRAM
NVidia Geforce FX 5200 AGP

As I played the game, over time textures were replaced with white squares. This affected all types of terxtures (units, buildings, terrain, controls, pictures, fog of war, everything)

The below console ouput occured when running Beryl as the window manger under gnome on an xorg-xgl server (same in game problem when running metacity on top of xgl, but no errors)

Globulation 2 was running in full screen OpenGL mode 1024x768 resolution

Game runs properly on OpenGL when running normal Xorg (no XGl)

This bug should be reproducible by running Globutation 2 on an XGL Xorg server.
