Flex TextRange performance issue on Linux
Earlier this month I mentioned I have found an issue with mx.controls.textClasses.TextRange class. This problem was identified on Linux (Ubuntu 8.10 and 9.04 using Flash Player 10,0,22,87) and could not be replicated on Windows Vista and 7 with latest Flash Player. I had no chance to test it on OSX.

To visualize the problem I am using the code from my previous article, Building an SQL tokenizer in Flex, ported to AIR. I am just using a bit more SQL code. Once the application is started, placing the cursor in the TextArea and hitting CTRL+A causes the AIR application to be unresponsive. It stays like that for about 20, 30 seconds, in fact any attempt to change the selection repeats the issue.
The source of the test application can be downloaded from here. I tried logging a bug but it appears I can create an account in Adobe JIRA but I am not allowed to log in.

That’s a bummer of a bug!
Jira sends a confirmation email. Did you get that? Maybe it got caught by your spam filter?
