Window Transparency Problems

[Bluehand]

Hi Everyone! Its been a while for me here. Anyway, I just downloaded the latest weekly build and have been having issues with what I think is window transparency handling in the tech screen. There appears to be a problem with the Planets window as well.
Using 0.4.5+ (build 2016-02-28.1df7cf9) on Mac OSX 10.10

After some more playing around I discovered its only if I have any tech enqueued that this happens, when the tech queue is empty it all goes back to normal, including the planets window.

Weird. I'm on 10.10 too, and everything works perfectly here. What are your system specs? Especially graphics subsystem.

Can you try to find out which test build introduced the issue? That too might help narrowing down the cause.

Narrowing it to a specific test build might not really help much, as I think these issues are due to the rendering state being left in an unexpected state after something renders itself, which causes something else later to not render properly... Really, to resolve these issues, someone who has them needs to be willing and able to go in and modify various rendering state calls and test interactively. My first attempt would be putting calls to enable/disable as appropriate all of

Code: Select all

    glEnableClientState(GL_VERTEX_ARRAY);
    glEnableClientState(GL_COLOR_ARRAY);
    glDisableClientState(GL_TEXTURE_COORD_ARRAY);

after each

Code: Select all

    glPushClientAttrib(GL_CLIENT_ALL_ATTRIB_BITS);

Starting with the Render functions of whatever isn't being rendered properly. (Enable whatever isn't being enabled by the existing code.) That should hopefully reduce the impact of the previous rendering state on how something renders itself.

I'm happy to try to figure out and address the issue, but unfortunately I don't understand what Geoff has described. The last version I played was before the 0.4.5 release. I'll check some earlier builds for the problem.

The issue is present in the Sept 22 2015 Mac OSX build, but not Sept 14 2015 or before. Looking at the Github commits, there's a couple rendering changes that could have something to do with it, but I don't know enough to be certain.

...I don't understand what Geoff has described.

In GG/src/DrawUtil.cpp around line 84 in the void Rectangle(...) function, try adding glDisableClientState calls so the block looks like:

Code: Select all

        glDisable(GL_TEXTURE_2D);
        glPushClientAttrib(GL_CLIENT_ALL_ATTRIB_BITS);
        glEnableClientState(GL_VERTEX_ARRAY);
        glDisableClientState(GL_COLOR_ARRAY);
        glDisableClientState(GL_TEXTURE_COORD_ARRAY);

I never got around to compiling with the suggested changes, but it appears to be fixed in the latest weekly build, so thanks for the help and kodus to whoever fixed it.
