First let me say that i couldn't find anything else,just the lag/jerk thing and
the interference,no problems in how the paint is applied.But i've not tried
every possible combination of modes,camera angles,brush sizes and so on,
of course.
Switching off the Tablet PC i got rid of the above mentioned pen icon appearing.
And just like Tibbar said unchecking the features in the pen and input settings
stopped the lag/jerk.Right click,for instance,is executed when you hold the pen
in place for a moment,which makes the context menue open
up.So it's like the
vista pen settings seem to override the settings of the tablet/pen itself,at least
in some applications.
I've tested it with TG2 Beta,v0.9x,Bryce5 and XSI Foundation.XSI is not affected
at all ,in Bryce and v0.9x the lag/jerk is hardly noticeable,it's more like a subtle
fade in of the stroke,i had to try it twice before i was sure that there is a difference.
In TG2 Beta the effect is much stronger,see example below (the strokes start is
on the upper end and they were rather slow;it might be possible that stroke speed
contributes occasionally,because there is some feature in vista's pen settings that
depends on movement direction and/or speed,not sure though).
So the award goes to vista here,i guess.
No idea why XSI is not affected or why it's stronger in TG2,that's beyond my horizon.
