Please see attached example, index.html. The bug can be reproduced with Safari 5.1.7 but not with Chromium. 869779 1 196636 scerveau 2013-04-05 08:32:31 -0700 Created attachment 196636 sample html test with log in document 901024 2 arurajku 2013-06-17 07:12:28 -0700 screen object's properties are readonly. Refer Screen.idl !

Right, they are readonly so you shouldn't be able to change them, thus the bug :) I am however unable to reproduce with the test case given and the EFL port (also using JSC). 901028 4 arurajku 2013-06-17 07:28:46 -0700 I tried in Qt Port, it is not changing. (If possible check the same in Slim Boat, it uses Qt WebKit) 901144 5 benjamin 2013-06-17 12:45:10 -0700 The test case does not return anything wrong on OS X.
