Bug Report

On KDE Plasma Wayland, every other scroll event fires twice regardless of scroll direction. Scrolling up or down, the pattern is consistent: one normal scroll, one doubled scroll, alternating.

Investigation:

Verified Wayland protocol events are clean using wev. No duplicate events at the compositor level, ruling out KDE/Plasma as the source
Cleanroom's bundled libglfw.so contains glfwGetPreeditCursorRectangle which doesn't exist in any public GLFW release, making system GLFW overrides impossible with -Dorg.lwjgl.glfw.libname
Built a custom GLFW from the LWJGL-CI fork with various scroll fix patches applied (time-based deduplication, GLFW_PENDING_DISCRETE/GLFW_PENDING_SCROLL flag clearing). None resolved the issue
-Dorg.lwjgl.glfw.scroll_scale=1 and -Dorg.lwjgl.glfw.enable_high_resolution_scrolling=false have no effect
Issue is reproducible on a clean instance, ruling out mod interference
Suspected source is LWJGL's Java-level event handling rather than GLFW
