Mode 2 (RenderVKProjectorShadows=2): a static projector blinked on/off on trees/ground after much of the sim had loaded. Not reproduced since a69deff434 (fragment-stage barrier on instance/VBO/IBO stream copies + RT selection hysteresis).

If it recurs: RenderVKRTDebugFlicker=1 + RenderVKDebugView=15 at the light, then grep the log for VKRTFLICKER.

Not reproduced since a69deff434 (fragment-stage barrier on instance/VBO/IBO stream copies + RT projector selection hysteresis), including after roaming the sim to load all lights. Closing as fixed; reopen if it recurs (debug: RenderVKRTDebugFlicker=1 + RenderVKDebugView=15).
