The SH1106 path always pushed the full 1 KB buffer over I2C every endFrame, even on static screens (clock, home) that don't change between updates. Hash the GFX buffer (FNV-1a, no external dep — the CRC32 lib is only wired into e-ink builds) and skip display.display() when it matches the last frame pushed. _force_redraw forces a flush on the first frame and after turnOn()/clear() so a post-wake or post-clear frame can't be wrongly skipped. Mirrors the existing e-ink CRC-skip. Builds green: WioTrackerL1_companion_solo_dual. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
