At first I though it was a software concern with the image of Deluxe Paint that I downloaded. Moving the mouse across the screen would simply erase anything it passed over. Erases the loaded image, erases the menus, everything. But the menus still work when I click where I think they would have been..
Moving on to getting some games, I got Questron II for the IIgs. Same thing! moving the mouse erases the pixels it passes over. Again all the menus and screen clicks work.
So I am left thinking this is a hardware issue. The IIgs currently has an Apple memory card with 1MB of chips on it. I have a 4MB card coming in the mail, but the more I think about it...
Is maybe the original IIgs monitor I am using having trouble with redraw after mouse movement? During regular IIgs desktop usage without hi-res graphics there is no issue. AppleWorks IIgs works fine, for example.
Anyone ever see something like this?

I am very new to the IIgs and hadn't heard of shift-boot before reading your post.
The motherboard is an early ROM01. I say early because it has the keyboard socket installed from the factory in case the motherboard was installed in a IIe/IIgs upgrade.
After my last post, I found I had to re-enable EasyAccess and leave CloseView disabled. Now all seems to be working correctly.
