[etoys-notify] [JIRA] Updated: (SQ-865) Pen mandala is not visible

[Bert Freudenberg (JIRA)]

     [ http://tracker.squeakland.org/browse/SQ-865?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Bert Freudenberg updated SQ-865:
--------------------------------

    Fix Version/s: etoys 2011
                       (was: etoys 4.1.1)

This is the case ever since we enabled display scaling. If you draw directly onto the display you need to explicitly push the pixels:

Display forceToScreen 

A possible solution would be catching display writes outside the Morphic draw loop and doing the forceToScreen automatically. However, that normally (when unscaled) happens in the copyBits primitive in the VM and it would possibly be quite expensive to implement  in the image.

> Drag a Rectangle and TextMorph into the project.
> Type the following statement in a TextMorph
>     Pen new mandala: 35
> and press CTRL+D. A beautiful pattern appears on the screen in Etoys 4.1#2353 but not in Etoys 4.1#2384 or 4.1#2390 (aka 4.1.1). If the Rectangle morph is dragged around the screen, the mandala reveals itself in parts. This was observed on Linux edition.
