Hi,
The following code snipped shows my actual problem: it seems to me as if the mesh engine does affect the settings of e.g. a line like linecapmode, smooth, … Please try that, if you can repeat that problem? Does someone has an explanation for that? Or am I simply doing something wrong? The text describes the effect which I do have.
Thanks!
-- Use this function to perform your initial setup

text="This small demo shows that probably the mesh engine does change the "
text = text .."drawing settings. I have no idea how to correct that. "
text = text .."It also seems as if the new settings are ignored ...\
"
text = text .."If you switch the flag from 0 to 1 please "
text = text .."inspect the endpoints of the line segments. They change from a "
text = text .."visible black gap inbetween (which is strange) to the wanted "
text = text .."dot at each line-end. Also smooth() seems to be affected. "
text = text .."You can see that the line itself gets blurred. \
\
"
text = text .."Another thing is the Output window on left side of screen. "
text = text .."If I open Codea the first time and run the code the text is unfocussed. "
text = text .."This can be corrected, if I completely shrink the window size first, and then "
text = text .."go back to the default size (using gestures)."
