Please confirm that mach5 is green. src/java.desktop/macosx/native/libawt_lwawt/java2d/metal/MTLLayer.m line 286: > 284: if (layer == NULL || ctx == NULL) { > 285: J2dTraceLn(J2D_TRACE_VERBOSE, "MTLLayer_blit : Layer or Context > is null"); > 286: [layer stopDisplayLink]; What happens if we exit before this "blitTexture" is called? Do not we need to stop(w/o possibility to restart it) that thread on toolkit shutdown or something like this? ------------- PR: https://git.openjdk.java.net/jdk17/pull/175
