MINIGUI 5.0.18 RELEASED!

On Oct. 17, 2026, FMSoft announces the availability of MiniGUI 5.0.18, which is a bugfix release with some enhancements of MiniGUI 5.0.x.

In this version, we made some enhancements:

ENHANCEMENTS:
- Add DRM surface lease APIs for native GPU rendering into DRM-backed device contexts, with DMA-BUF export and release fence synchronization.
- Support dumb-buffer hardware surface allocation and PRIME export in the built-in DRM path.
OPTIMIZATION:
- Copy only the accumulated damage bounding rectangle in the built-in DRM shadow-to-scanout path under non-compositing schemas.
- Improve pixel copying with correct pitch, offset, and bounds handling, and add DMA-BUF CPU read synchronization.
BUGFIXING:
- Fix DRM device initialization failures caused by platform-driver name mismatches on Rockchip and similar SoCs.
- Fix scanout buffer ownership and pending damage handling during page flips.
- Fix synchronous page flips when DirtyFB is unavailable and prevent incorrect flipping in single-buffer mode.
- Fix DRM software cursor rendering and synchronization between native drawing and GDI operations.
- Fix lost touch positions and press/release events in buffered singletouchkey input.
- Fix invalid touch slot queries for libinput TOUCH_FRAME events.
TESTS AND DOCUMENTATION:
- Add regression tests for DRM damage updates, buffer synchronization, and surface lease locking.
- Document DRM damage update behavior and RK3566 acceptance checks.
