Hi,
It is also possible to see Trachel classes involved, so maybe there is a problem with some Roassal code.

Do you have some way to reproduce it??

Cheers,
Alejandro

Hi,

I think the problem is that your Pharo30.sources are not available. Could it be?

Hi Natalia,

did you try to bring up the halo menu and select "debug drawing error"?

This error looks like AthensCairoMatrix translateBy is called with wrong argument type.
This may happen if it is called with a fraction instead of a float type.

Hello.
I���m working with graphics. Usually if i have some problem I got the debugger window, however some times it gives me the red rectangle error. I cannot understand from it what is the problem.
What should I do in such case, maybe there is some way to get this signalError in debugger?

Best regards,
Natalia

P.S. Here I attach the error I got.
