I have actually tried the recommended way of double buffering "by the book" in the past, using messagePorts for each of the the 2 buffers ("Safe to display" and "Safe to write").
(Without any WaitTOF() at all in the loop..).
But it doesn't help; Same results.

As mentioned, I don't do any graphics ...

I use this type of doublebuffering:
- 2 buffers (front & back), allocated by IIntuition->AllocScreenBuffer().
- Image blitting etc. only on the back buffer

Concept in the loop:
1. WaitTOF()
2. Makes the backbuffer visible by swapping the 2 buffers (using IIntuition->ChangeScreenBuffer())
3. Copies ...

When single buffering, the glitches appear on the top. How far down, depends on how delayed the vertical blanking finalization is.
With double buffering, it appear for the whole screen of course (as buffer swapping gets delayed).

The strange thing is that this happen's even when CPU-load is at idle ...

Hello,


I have the following issue on my AmigaOS4-system:
Occasional "stuttering" in graphics animations (f.ex. in 2D horisontal screen scrolling, using blitting operations).

and
2) the GUI Preference option "Window refresh type" is set to "Smart" (the "GUI preferences window, subsystem "Options").

In the "GUI preferences" window, subsystem ...

Ok. Now I have changed the WINDOW tooltype as you described it, and made a new test, but the behaviour is still the same.

You are somehow opening the console window with "Smart" refresh. Please tell how you are opening the Shell.
The Shell is started by clicking on the Shell-icon in my AmiDock (the same that is available from the Workbench/System folder).

Below are tests that shows what happens with different GUI ...

After upgrading to update 5 of OS4.1, I have experienced problems with the default Shell.
There are 2 issues:
1) Copying text from the shell doesn't work (but paste does).
2) When shrinking the size of the shell window, and then making the window larger, all text that got cleared during the ...
