Newly compiled Pioneer has a inconsistent graphics bug with speedlines enabled #4151

Open macksting opened 7 years ago

macksting commented 7 years ago

Observed behaviour

After undocking from Discovery Base in a Nerodia, there's a funny white line in space as I exit. It starts about 400m out and persists until the reference frame swaps to Jupiter 15 km later. Turns with the ship as the ship rotates, it seems. Only crops up when speed lines are enabled; turning off all pretties except speed lines leaves it in place. Turning or lifting landing gear leaves it intact until reference changes; invisible from any angles except bow and stern camera.

Expected behaviour

No funny lines after leaving the station.

Steps to reproduce

Undock from a very specific large dock, not just any will do, in Discovery Base, with speed lines enabled.

My pioneer version (and OS): build: git (f1f4f71) and (ab51dca) on lubuntu 16.04

This works fine for me (Windows 10/nVidia) so it might be GPU/Linux issue.

speedlinebug.zip Zipped save file. Tried to upload this before, but apparently mucked it up. Worth a shot, see if it does it for you?

fluffyfreak commented 7 years ago

That's bizarre I get it with your savegame too! I'll have to debug that one.

I've noticed this on the Barnard's Star start too, as soon as I move away from the initial direction, it gets less pronounced. Looks to me like some sort of singularity in the streak line code.

ColdSpirit0 commented 6 years ago

See that issue too; Win7, intel hd610 Looks like lines generated not so randomly

fluffyfreak commented 6 years ago

Damn, that save game file seems to be rather corrupt. In release the game gets past the asserts, with debug info it usually crashes, and in full debug mode it just fails with the wrong starport/station information etc.

fluffyfreak commented 6 years ago

Is anyone who gets this bug able/willing to debug it? The file you'll be wanting to stick breakpoints in is Speedlines.cpp, and there's only two really interesting methods in there, Update and Render.
