Something not working in GZDoom that's not a bug? Is the display a bit quirky and unexpected? Post here.

[2.3pre-918] 4 Visual Bugs with old hardware that don't occur in 1.10pre-1359

On my old 10 year old notebook computer, I'm encountering 4 visual bugs in gzdoom-x64-g2.3pre-918-g48d17f8 that I don't encounter in gzdoom-g1.10pre-1359-g6a8e60c

The computer's stats are

AMD Turion 64 X2 TL-50 processor
ATI Radeon Xpress Series integrated graphics
2GB RAM
Windows Vista Ultimate 64-bit

1 - Random walls in levels will render as white.

2 - The texture that surrunds the the status bar renders as white.

3 - The fuzz invisibility effect shows up as no effect at all instead of defaulting to the shadow invisibility effect.

4 - The invulnerability effect is being rendered as an inverted colors/negative image instead of a grayscale inverted colors/negative image. I'm not sure if this is a bug or an intentional change.

4 is an intentional change because doing this right on old hardware would have necessitated duplicating all textures and a lot of overhead in code I consider legacy support. The color inversion is nearly free of overhead.
I can't say much about the other issues, I do not own any hardware old enough to see what happens here which means I have no means to fix it.

Moved to Tech support because this looks like a driver issue and maybe someone has an idea.

The colored invulnerability effect is not a driver issue, that's present if you type -glversion 2.0.

As for the others, I don't know unfortunately.
