I used to use PowerDesk 4.x with my trusty old Matrox Millennium (I). When I upgraded to PowerDesk 5.13 for my new G400, one of the things I really liked about the new driver was a great improvement in the "PixelTOUCH" feature. With PowerDesk 4.x, my monitor would lose sync and go blank for about one second every time I changed the zoom level. With PowerDesk 5.13, zooming was now literally instantaneous, bringing the perceived responsiveness to a whole new level, especially when doing heavy image editing (something I do a lot).
Imagine my dismay when I discovered that the new PowerDesk 5.21 breaks this new feature, causing the monitor to once again lose sync and go blank every single time I change zoom levels! Now that I've gotten used to the instant response of 5.13, it's driving me crazy!
I've since discovered, however, that the feature isn't always broken under 5.21. Specifically, it will work the way it should if, and only if:
a. I'm currently using DualHead Clone; or
b. I'm currently using DualHead Zoom.
As long as Clone or Zoom is enabled and in use, PixelTOUCH works beautifully. However, the very instant I, say, switch off Zoom (using the assigned hotkey), PixelTOUCH once again reverts to the "broken" behavior.
So the current workaround is to make sure that I've always got Zoom activated, even when I'm not actually using it. (Simply turning on Clone is not an option for me, as I'm running at 1792x1344, which Clone doesn't support.) It's pretty annoying to have to remember to press the Zoom hotkey (and then define a "dummy" zoom region) every time I boot up or return to the Desktop from a game.
Matrox, if you're listening, is there going to be a fix for this? I for one would be extremely grateful!
