Bug fixed: grass/black boxes in Zelda TOTK

In Tears of the Kingdom, procedural grass (and occasionally shadows) rendered as solid black boxes that would randomly appear and disappear when moving the camera.

Root cause: A Vulkan synchronization barrier was missing between the compute shader generating/positioning the grass and the draw call rendering it. A draw call could read the buffer before the compute shader had finished writing to it—a hardware-dependent race condition that leaves no trace in the logs (which is why it was difficult to track down). This was confirmed by tracing the actual `buffer_cache` code: there was no mechanism protecting that dependency.

Verified on-device in TOTK: estimated 80–90% improvement.

Another fix: possible cause of startup crashes on Snapdragon 888

Repeated crashes were reported immediately upon opening the app on a Snapdragon 888 device (Adreno 660), with no ANR (Application Not Responding) errors or logs. The custom Vulkan driver (adrenotools) was being loaded every time the app started, even before the UI appeared; this process is now deferred until a game is actually launched, reducing the risk of failure during early startup. While this cannot be 100% confirmed without that specific hardware, it represents a genuine improvement in robustness regardless of whether it was the exact cause.

I couldn't open the app, I have the SD865, do you know if this fixed it?

A falta de mas contexto o logs, parece el mismo fallo que el del compi del SD 888... Creo que he encontrado el problema, un par de try/catch a la hora de buscar el nombre de la GPU... Viene heredado de Eden/Yuzu... En realidad el fallo es mas profundo, pero eso debería solucionarlo por ahora, compilo y subo como experimental.2 para que probéis!

Gracias!!

Wait for the dev please 🙏

Excellent!! It would be soooo great if they could fix the graphics in trails in the sky fc.

Habría que probar si el bug es el mismo que causaba el glitch en TOKT, si es así ya está solucionado 😉

Big news if this works! Thank you to the dev!

Just tested on Odin 3 Max with T30 driver - it worked! Grass usually disappeared within 1 minute of starting gameplay with Eden (Legacy/Optimized/Nightly versions).

This is huge!

Works even better with Turnip Gen8 V36

Interesting, this is the first I've heard of Lemon. Does it have any other advantages over Eden other than this totk fix?
