maxLoadedTileBytes

GPU-byte budget for the resident-tile cache. Because full-resolution WFS geometry makes tile VBO/EBOs wildly uneven, a flat tile count (maxLoadedTiles) lets a few dense tiles balloon GPU memory until the driver OOMs (KGSL mmap ENOMEM) while the Java heap still looks empty. A byte budget evicts on real footprint instead. Non-zero here overrides maxLoadedTiles; set 0 to fall back to the count bound.
