Weird (Renderer?) Visual Glitch

Postby ReX » Mon Jun 10, 2019 9:31 pm

I just encountered a weird visual glitch. Looking at an area at a certain angle shows everything as it ought to be. Lowering the field of view fractionally really messes up the view. Lowering the field of view again resolves the issue. So it's only when the view falls within a narrow angular range. This problem does not seem to happen from every possible viewpoint, but I haven't tried changing position too much.

GZDoom v3.7.2 Legacy; hardware acceleration (not an external video card)

Here is a normal view of the scene:

First and most obvious question is going to be - what is your GPU?

We should also know your operating system and what kind of CPU you have.

Also important:

What map?
What does the modern build do?

@Rachael: I can’t check right now but will send info as soon as I can.

@Graf: 1. It’s a custom map (WIP), which I can send you if needed
2. I haven’t used the newest build, but I’ll download, try out, and report back

I'll still need the map to analyze the problem.
