I downloaded all the latest Windows 7 updates for an unrelated issue about 3 weeks ago. So I think that means my drivers are up to date.
My Windows setting is set to best performance - with no “eye candy”.
Regarding specific icons, I have a favourite Rickenbacker bass icon for my bass tracks. It was always pixelated. But if I loaded it into track 1 it didn’t pixelate. I tried a few icons – all Sonar standard icons, including simple ones like a french horn from the Brass folder – they ALL pixelated upon reopening the project, and they were all fine when I reloaded the icon.
I used Sonar’s icons for all serious projects in 8.5 and none pixelated.
Like I said in my previous post, I tested the “template theory” by starting a new project using a simple template that had no icons; then I added icons afterward. The icons still pixelated upon reopening the file.
I think the tree we have to bark up is why the pixilation is fixed upon reloading an icon. Why would a computer with graphics issues be fine again just because an icon has been loaded a second time?
Also, I think the reason this hasn’t been overly reported is as the OP stated: “No big deal...just curious”. Apparently people who have the problem seem to just put up with it. And I would guess a fair percentage of folks don’t use icons?
Hope this helps.
