X-Plane 12.4.3 Release Notes

Welcome to X-Plane 12.4.3 – The VR Release!

Notams

• Apple Vision Pro Support requires a dedicated FREE app from the App Store
• Hand-Tracking and Eye-Tracking is only compatible on headsets with the required Open-XR Extensions
• Meta Quest 3 is not natively compatible with Hand and Eye-Tracking (Due to OpenXR software limitations with the headset)
• Virtual Desktop currently has alignment issues with the Meta Quest 3 in X-Plane 12.4.3. We are in contact with the developer to find a solution

Version History

Release Date: May 21, 2026

ATC

• The calculation of the estimated radio strength will no longer cause a crash

Graphics Engine

• A warning is now shown at startup if the user has a Raptor Lake CPU with unstable microcode
• Fixed a memory leak when running on macOS
• Implemented various fixes to improve stability

VR

• The G-loaded camera now works again in VR mode (XPD-18131)
• Yoke manipulators will latch/unlatch correctly again (XPD-18142)
• Fixed a camera issue in VR when changing aircraft while using real-world weather (XPD-18082)
• Improved the alignment of Meta Quest 2 and Quest 3 controllers (XPD-18134)
• On Apple Vision Pro, the virtual hand mesh is now hidden when visionOS shows your real arm through passthrough, so you no longer see a virtual hand stacked on top of your real one (XPD-18107)
• Refreshed the VR radial menu with dedicated icons for the MR sub-buttons and adjusted spacing for a consistent layout across all sub-menus
• Hand Tracking, VRS, and Mixed Reality capability warnings in VR Settings now use a clearer, more visible badge style consistent with other warnings on the page

Weather

• Fixed a memory leak in the real-weather downloader

SDK

• XPLMPluginReload will no longer cause a reload loop (XPD-18139)
• Temporarily removed threading checks for XPLMGetNthPlugin, XPLMReloadPlugins, and XPLMIsFeatureEnabled to avoid breaking existing plugins; these checks will be re-enabled in the next major release

Release Date: May 14, 2026

AI Aircraft

• Fixed a bug where the number of AI Aircraft doubled when starting a new flight (XPD-18115)

ATC

• Fixed a bug where the user could not enter a space when filing a flight plan (XPD-18113)

Graphics Engine

• Fixed display of glass objects inside cockpits (XPD-18110)
• Fixed a crash when using three or more monitors at the same time

Systems

• Fixed a bug where the bird strike failure would no longer show birds (XPD-18104)
• Fixed a bug where a custom OBJ attached to a weapon would not load a custom dataref correctly (XPD-18064)

VR

• Fixed contour-draw in MR setup so pinching toolbar buttons no longer accidentally erases your drawing; added a clearer Cancel | Redraw | Done toolbar and on-screen instructions
• Fixed passthrough bleed-through on Quest 3 caused by a leftover mask from other headsets; MR options are now correctly shown only on supported hardware
• Renamed the radial menu MR toggle to “Enable/Disable MR” for consistency with other radial menu actions
• Reworked the MR setup toolbar with a clearer two-row layout; setup changes are now only saved when you press Done, and Cancel fully reverts your mask and alignment back to how they were
• Updated to the latest OpenXR runtime and NVIDIA NVStreamManager SDK
• Fixed alignment drift on Apple Vision Pro when reconnecting; your saved alignment is now preserved instead of being subtly shifted on every reconnect
• Fixed cockpit and mask drift after pause/resume on Apple Vision Pro; recentering your view is now nearly instant (previously up to half a second)
• Fixed fast, deliberate pokes occasionally being ignored as “too slow”
• VRS will no longer be shown as activated if it’s not supported by the used VR headset (XPD-18109)

SDK

• Fixed a problem when using custom avionic devices in VR as pop-out (XPD-17503)
• Calling XPLMDestroyWindow with a valid window ID will no longer cause errors in the log file (XPD-18105)
• XPLMUnregisterFlightLoopCallback will unregister the callback again as intended (XPD-18102)

Release Date: May 8, 2026

ATC

• Fixed default ATIS transmissions to include transition altitude/level and RVR information regardless of distance from the airport (XPD-18013)

Avionics & Systems

• Fixed a crash when selecting PLN mode on but_map_mode_HSI without a flight plan (XPD-18045)

• Trigger gear down warning again in multi-engine aircraft after setting another engine to idle (XPD-18027)
• Fixed an A330 FCU bug where pressing the HDG V/S–TRK FPA pushbutton with both FDs off failed to toggle the FPV and instead caused the selected HDG value to drift incorrectly with each press (XPD-18031)
• Fixed an issue where the EGT and CHT bars and graphs weren’t drawn correctly on the MFD->Engine->Lean page of the X1000 (XPD-17956)
