Comment 3 for bug 582106

What is your Pinta version? I have tested this on Pinta latest development on Ubuntu 12.04 LTS and I have no issue at all. I have been using Pinta/Ubuntu for years and I have never seen this kind of problem.

Don't know maybe some specific problem to your configuration (graphic drivers etc)...

The only think I can imagine is if working with very large images like 2000 x 2000 and then I notice some performance drop in selection tool, like a second delay, but this is reasonable because of using old notebook running inside virtual machine.

Can you please specify what is your image size and what does "very slow" mean, is this taking some seconds, how many seconds it takes... Is it slow when drawing (like displaying step-by-step rectangle) or slow only with drawing.
