Hi @matyalatte

Thank you for sharing your project.

I tried this rubiks cube program on Ubuntu.
I found that the program crashes when I move the mouse over the window.
It crashes on the following line

https://github.com/libui-ng/libui-ng/blob/ac1c0d55f8da2dcacb6bc7a4da7702176d0de2da/unix/area.c#L311

static gboolean onCrossing(areaWidget *aw, int left)
{
	uiArea *a = aw->a;

	(*(a->ah->MouseCrossed))(a->ah, a, left);     // here
	uiprivClickCounterReset(a->cc);
	return GDK_EVENT_PROPAGATE;
}

(gdb) print a
$1 = (uiA$1 = (uiArea *) 0x63e0b0
(gdb) print a->ah
$2 = (uiAreaHandler *) 0x7fffffffd970
(gdb) print a->ah->MouseCrossed
$3 = (void (*)(uiAreaHandler *, uiArea *, int)) 0x7fffffffd9a0

Thread 1 Thread 1 "libui_rubiks_de" received signal SIGSEGV, Segmentation fault.
0x00007fffffffd9a0 in ?? ()

If it works fine on non-Unix platforms, it may be a potential bug in libui-ng?
