When you upload an extension via extension manager, set proper permissions works only on first level folder, but dont work recursively.

LocalConfiguration.php option:

'createGroup' => 'mygroup',
'fileCreateMask' => '0664',
'folderCreateMask' => '0777'

are set only on first level folder of via extension managerer uploaded extension but not applied recursively on subfolder and files.
