Today, I have chance to test new Audacity 2.1.2. The shift to wxwidget 3 bring some benefits to RTL languages such as Arabic. Here is the old audacity screenshot in Arabic:

and Audacity 2.1.2 using wxwidget 3 screenshot:

as you can seen, main menu is the right position. However, there are some areas (highlighted in red below ) set to RTL wrongly and now they are not even readable for RTL users.

I tried to submit this problem in bug report system but the registration not open.
I am looking for help from devs.

Thanks for your report. These problems appear to be similar to those reported on Windows too.
This policy is to prevent spam and prevent posting of non-bugs by users who merely want help using Audacity.
If you are not a developer, but are able to compile Audacity and provide detailed feedback for any fixes we make, then we can provide you with a Bugzilla account.

You maybe mean Linux. I am afraid that the problem from wxwidgets itself. Please have look to this bug against wxGTK in linux.
I can do that but in linux only (Ubuntu). Right now I just have Window 7 in my virtualbox. please let me know if any developer makes fix for this problem, so I can provide my feedback.
