Loading times much longer with OpenGL than SDL on Linux about wyrmgus HOT 2 OPEN

Other users have reported this issue as well. I'm not sure why it happens though, and it does seem to be Linux-specific. Maybe the graphics are being improperly freed after a scenario on Linux, causing them to need to be reloaded every time?

Regarding loss of functionality, the Steam overlay works only if OpenGL is active, but not with SDL. Using OpenGL also improves the game's performance significantly.

I've checked the instances where the graphics are freed, but the only one that had Linux-specific graphic freeing (InitVideoSDL()) is only called once, when the game starts.

I then looked at the unit type's CGraphic loading, but, well, if the graphic has a Surface, the CGraphic::Load function returns right at the beginning. Same thing for OpenGL texture creation, it returns if a texture is already present for that CGraphic.
