Intermittent Visual Corruption JKA / OpenJK

[triplex]

Hello,

I am having an issue where there is an intermittent visual tearing / blanking out whilst playing JKA.

I have no idea where it is coming from and I have tried both with my favourite setup and also with a brand new vanilla install of JKA and am still getting this tearing effect.

It also seems to be somewhat specific to certain views / angles which makes me think it is something map-based, but having tried a fresh install and still getting it, that doesn't explain it.

See video here for an example:

I have also checked the command window for any warnings that may explain what's going on, but there are none.

Has anyone seen something like this and has any idea what I should try?

Thanks very much!

Seems like a graphics driver issue of some kind? See if you have updates to them or maybe try rolling them back to a previous version.

I've also had issues like this from failing graphics cards. Try the drivers first, though.

For the record, what graphics hardware are you using?

Hmm interesting.

I have an AMD Radeon Rx580. Not particularly old, though my PC in general is getting on a bit (despite upgrading everything over the years), and am probably in need of a bigger PC that can fit some better tech.

However, this phenomenon doesn't seem to repeat itself over other games & software I have installed, though it is the only IDT3 / Quake-based game I have played in recent times.

- so it's possible that maybe the latest AMD drivers for my card have a bug in the OpenGL support.

I will try a full clean uninstall and reinstall of my graphics drivers and see if that makes any improvement.

Yeah, if it was a hardware failure you'd see it in all kinds of things, not just JA. Has to be some weird software issue.

Try a BIOS update, too. Some AMD graphics cards don't work correctly without one. Probably unrelated, but who knows.
