Checklist
- [X] Test in the latest git build in case it's already fixed.
- [X] Search for other reports of the same issue.
- [X] Try resetting settings or older versions and include if the issue is related.
- [X] Try changing graphics settings to determine if one causes the glitch (especially speed hacks or enhancements/replacements.)
- [X] Include logs or screenshots of issue.
Yeah, I'm not testing much with it off, I highly recommend to turn on buffered rendering. But I'll fix it of course.
Tekken 6 is crashing on the latest build if set to skip buffers rendering!
Juice 2 is also crashing using skip buffers rendering and some other games I tried.
So the issue here is that the line is actually drawn, it's just so ridiculously thin that it doesn't cover more than a pixel or two, so something is wrong with the line expansion math. The GE dump reproduces the error perfectly.
The following change makes it look good, which is of course a ridiculous change to make:
Vec2f addWidth = Vec2f(-vertical, horizontal).Normalized() * 10000.0f;
The beam looks like this on a PSP:
The software renderer (with #16066) gets close, just slightly off:
The line drawn at 5780/5813 uses addWidth: 0.985653,0.168787 dx/dy: 0.004167,0.007353, or 0.00410721605 width for the rectangle. That's slightly less than 1 pixel. In renderdoc, it's the last indexed draw in the first render pass.
But in the render doc the positions are not different, however. There's only two unique xyzw values going in or out of the vertex shader. Which now makes sense, because of course, w. That's why it's not adding anything after transform. D'oh.

I can exibit this issue again in the recent build.
