Not sure if this is helpful, but I've interestingly seen this error before on Firestorm on Linux, the same exact texture dimensions as well.
I have suspicions that it is a UI element due to the texture size.

It's occurred in several regions, so it probably isn't isolated to "Danger! Danger!".
I've had issues trying to reproduce it though, restarting the viewer makes it go away, so troubleshooting it is a pain.

Added logging to hopefully catch which textures suffer from this.
