Bug on XML Browser Image display

[Tercio]

I was using the following XML to display an image in the screen of several T46S phones.

The image has 480 x 270 pixels and was displayed "fullscreen"(Despite de fact it was using mode="regular") with soft keys on it. I cannot use mode=fullscreen because it hides the softkeys.

After upgrading from firmware 66.83.0.35 to 66.84.0.15, the image was occupying only half of the screen, the center part of it(Both aligns middle)

Code:

<?xml version="1.0" encoding="ISO-8859-1"?>
<YealinkIPPhoneImageScreen Beep="no" Timeout="5" LockIn="no" mode="regular">
    <Image verticalAlign="middle" horizontalAlign="middle">http://camera.office.local/cam.jpg</Image>
    <SoftKey index="1">
        <Label>Update</Label>
        <URI>http://camera.office.local/cam.xml</URI>
    </SoftKey>
    <SoftKey index="2">
        <Label>Pickup</Label>
        <URI>Dial:55</URI>
    </SoftKey>
</YealinkIPPhoneImageScreen>
