Window width > screen width ?

Is it correct that I may not have a window that is wider than the screen? If I drag a window to the left and out, I can't extend it to the right hand side. It didn't matter whether I activate easy dragging outside the screen in "GUI" or press shift to do it.

I found out it is incorrect. But I noticed two MUI applications didn't allow a wide window, AmigaShell did. When the shell window was overwide, moving it went super sluggish. That is with hardware compositing and about 90 MB VRAM available.

On AmigaOS you can't have a window wider than the screen ... until recently.

The 3.1.4 version of intuition.library will let you do it and so does AmigaOS 4.x.

Yes indeed you can have a window that is wider thn the screen.

You probably increased the windows bitmaps width to wider than the limit for hardware compositing. (which varies from card to card) .

@broadblues

Then I'm guessing the compositing limit is 1920 wide in my case (newshell command doesn't seem to do this, or I do not know about it, so it's set manually).

@Thematic

It's probably 2048 (2k), but window bitmaps are a bit larger than the window size (allowing for shadows etc) so the practical limit for screen and window size is a bit less than that.

On my SAM with a R9250 card I can in principle just get a HD (1920x1080) screen (though I have a older 1280 sized monitor so don't try) so the practical limit is probably just alittle more than 1920 thus only a small increase in window size from the HD screen width will hit that limit.
