| #7669 | fixed | S3TC reported in OpenGL extensions, but not working | ||
| Description |
VirtualBox's OpenGL driver reports that it supports both GL_ARB_texture_compression and GL_EXT_texture_compression_s3tc, but attempt to load compressed texture results in OpenGL error 1282 (invalid operation). Testcase: /* gcc dupa.c `sdl-config --libs --cflags` -lGL */

#include <GL/gl.h>
#include <GL/glext.h>

char* buf = malloc( 64 * 64 / 2);
memset( buf, 0, 64 * 64 / 2);
SDL_Init( SDL_INIT_VIDEO );
SDL_SetVideoMode( 64, 64, 24, SDL_OPENGL );
glGenTextures( 1, &tex );
glBindTexture( GL_TEXTURE_2D, tex );

| #7532 | obsolete | Max Screen Resolution | ||
| Description |
There is no reference in the User Manual regarding what max screen resolution can be, and no instruction how to get it. The intuitive, or shall I say the standard way, by setting it in the Guest, is not supported by VirtualBox. Rather, it is done unintuitively by setting Machine->Auto resize Guest Display (Host+G). Feedback on whether it has been done or not is then given by hiding a tick mark inside an icon. It is possible to do so, and technically-minded users should not have a problem with it. Better usability is achieved, for more users, by

| #8867 | duplicate | Can't control VM boot device between SATA HDD and IDE HDD | ||
| Description |
I have a VM setup with SATA HDD and later I added another virtual disk to the IDE interface as the slave to the CD-ROM. Even if the boot sequence was HDD only, VirtualBox searches for operating system on the IDE disk and then fails. Wasn't able to select which hdd to boot from from within VM configuration where we CAN select to boot from HDD or CDROM. |
