[lacks info] 3.7.1: Black screen blink

[CyberKlown28]

  every time I click during a game, the screen 'blinks' flashing a quick full screen of pure black for less than a second, but it's every single click. Only happens during actual gameplay, not in the menus.

It would be nice to know more information. In particular, the most important being the version of MegaGlest you are currently using. Also, ensure you have the latest drivers for all your hardware. I can't even directly link to a driver because the drivers for mobile cards differ from desktop cards, but you can driver utility here. Granted, the integrated graphics cards have their share of problems...

Anyway, it'd perhaps also be of use to know if the issue persists when playing in windowed mode (versus fullscreen). A quick google search reveals a chockload of similar flashing screens on integrated graphics, but few solutions beyond a discrete graphics card. Perhaps enabling logging (see the sticky post) may reveal something?

3.7.1
everything is updated on my hardware.

Maybe you enabled the Colorpicking selection mode somehow ? This is buggy in 3.7.1 .

things that may have switched this on is:
- you tested a svn version
- you set this manually in your glestuser.ini or glest.ini

Did you ?

[CyberKlown28]

Nope, just downloaded and fixed the resolution and stuff in-game to what I wanted, started playing. 

Not sure if it's helpful but annex: conquer the world also gives me this problem.
GAE 3.2 does not.

Did you try updating your gfx drivers ?

[CyberKlown28]

Yes all of my drivers are up to date.

I'm having the same or a similar issue on 3.7.1, however I'm on Linux 64-bit using a dedicated ATI video card and color picking. This issue is fixed for me on (and before) r4209.

CyberKlown28: It would be great is you could try a development build to see whether it fixes it for you. When you do, be sure to experiment with the three unit selection modes, not every type may work for you.

For me, only color picking is usable, with the old default rendering mode (GLSelectBuf) the game (development builds only, 3.7.1 behaves like frustrum picking in this mode) would segfault with:

Code: [Select]

megaglest: /home/tomreyn/SCM/megaglest-trunk/source/shared_lib/sources/graphics/gl/model_renderer_gl.cpp:40: virtual void Shared::Graphics::Gl::ModelRendererGl::begin(bool, bool, bool, bool, Shared::Graphics::MeshCallback*): Assertion »rendering == false« failed.Frustrum picking sends units to buildings whenever I right-click anywhere.

Update: I've uploaded a video (39 MB) displaying the issue I'm experiencing on 3.7.1 (but not on current development builds).
