[mythtv-users] MythConfirmationDialog scaling incorrectly when in OSD

Hi,

My MythConfirmationDialog is not scaling correctly when shown in an OSD.

This is when I do: mythutil --message --message_text hello --timeout 30
--bcastaddr 192.168.0.13

http://www.rozel.net/mythscreen.jpg

I used to be a developer on myth (a long time ago), contributing some minor
tweaks to the scheduler. So I've been looking at some of the code. However,
I'm now using the mythbuntu base distribution, on precise.

Here is a partial log

I've been able to figure out that it is using "MythConfirmationDialog".
This is defined as

    <window name="MythConfirmationDialog">
        <area>0,200,544,170</area>

        <animation trigger="AboutToShow">
            <section>
                <alpha start="0" end="255" easingcurve="OutQuart"/>
                <zoom start="0" end="100" easingcurve="OutQuart"/>
            </section>
        </animation>

        <animation trigger="AboutToHide">
            <section>
                <alpha start="255" end="0" easingcurve="InQuart"/>
                <zoom start="100" end="0" easingcurve="InQuart"/>
            </section>
        </animation>

        <imagetype name="backimg">
            <area>0,0,544,170</area>
            <filename>mythprogressdialog-background.png</filename>
        </imagetype>

        <textarea name="message" from="basetextarea">
            <area>10,10,534,90</area>
            <align>allcenter</align>
            <multiline>yes</multiline>
            <cutdown>no</cutdown>
        </textarea>

        <button name="cancel" from="basebutton">
            <position>90,110</position>
            <value>Cancel</value>
        </button>

        <button name="ok" from="basebutton">
            <position>338,110</position>
            <value>OK</value>
        </button>
    </window>

Unfortunately my HD tuner isn't working right now - I suspect it might
scale differently for HD channels. I did also notice some recent problems
with interactive TV scaling, but I don't use that.

The same thing happens on both of my frontend boxes, one is a self-built
PC, the other is an Acer nettop.

Any ideas?

Thanks
