[GFX driver bug] Visual glitch with rotate/move gizmos

[jinks]

Hey all,

I have a visual glitch with the new gizmos from 0.90. The "scale" part on the insides of the rings/arrows appears to have no transparency and instead shows the bright pink texture indicative of a color/chromakey overlay.

Mods or no mods makes no difference. The screenshot is from a complete re-install (Steam version).

Has anybody an idea what might be causing this? My GPU is a nVidia 560, using latest proprietary drivers. 32/64 bit version makes no difference either.

You're using -opengl mode I believe. I see the same thing with that selected.

I'm guessing you're using -force-opengl?

I actually had the same thing and posted about it (in general addons discussion because I thought maybe a mod was doing it): http://forum.kerbalspaceprogram.com/threads/111137-Purple-rings-with-the-rotate-and-offset-tool-in-VAB-SPH-What-mod-is-doing-this-Or-gfx-settings

Basically, it's just OpenGL not being supported (or something), but it's harmless, aside from making things a bit gaudy, according to one of the responses to my thread.

No, as the title says I'm using Linux. No mode-forcing or anything.

This would mean that OS X and Linux are 2nd-class citizens.

I think it's the unity engines fault though, not squad, and I'm a windows user.

Hi jinks (lol).

What you're seeing is actually caused by a bug in the proprietary Nvidia Linux driver, the gizmos display perfectly fine when using the open source nouveau driver on Nvidia hardware, or using non-Nvidia hardware and drivers.

I've notified the devs so hopefully they can render this differently, but really Nvidia need to patch their driver.

Interesting... I didn't think that you could even get OpenGL this wrong, it's lot like transparency is some hardly understood new development. Way to go Unity/nVidia

Since there's loads of other transparent things that work just fine in KSP I'm quite sure that it can be worked around - at least it's way more likely to get Squad doing something about it than nVidia

Yeah, there must be some other way to render that gizmo, it looks like an alpha mask to me, those typically use magenta as the "alpha" channel and simply don't draw it.
