foliage-linux-updater: constant fog flicker on AMD RX 7700 (video + log) #337
Description
System: RX 7700 (16 GB), Adrenalin 26.10.1, Ryzen 7 8700F, 16 GB RAM, Windows 11, 3440x1440, Ultrawide on.
Build: foliage-linux-updater (fresh build, caches cleared)
- Game runs great otherwise: foliage, Link's lighting, ultrawide, ~55 fps. Thank you!
- Default fog (fog patch now off by default) is extremely thick on AMD: Kokiri is nearly white.
- With
RX_VK_OOT_VISUAL=1,RX_VK_OOT_FOG=0.2,RX_VK_OOT_EXPOSURE=1.0it looks right, but the fog/haze flickers constantly. The background haze pulses brighter/dimmer every frame or two; foreground (Link, grass) is steady. Measured from a phone video of the monitor: frame-to-frame brightness swings of ~5-8% in the hazy area. - Matches "fog flicker" in the release's still-open list. I'll add the video and hookshot_log.txt in a comment below.

Thanks for the careful report and measurements. The haze pulsing brighter and dimmer is the exposure flicker tracked in #145: EvilBoyce's fix (CPU reads of GPU results now wait for the GPU work that writes them) is in the next release, coming soon. Fog and brightness that are too strong are followed in #36. Closing as a duplicate of #145; the video and log are welcome there.
