Perhaps in some laptops, x_max or y_max is odd when resolution is doubled, and rounded up or down in half-resolution mode, so multiplying the half-resolution size by 2 results in a slightly incorrect full size. I don't know if that's the case in other touchpads, but my laptop's touchpad has even size in full-resolution (doubled) mode, meaning it doesn't round its size in half-resolution mode (so multiplying both values by 2 would work on my machine).

My current patch re-queries x/y resolution after setting absolute mode. If this is the process that Elan's FW team recommends, should the patch be kept as-is?
