Dear, @LeonidS ,

here's the settings for my forum hashtag block still showing a list instead of a cloud.

array (

 'module' => 'system',

 'method' => 'keywords_cloud',

 'params' => 

 array (

  0 => 'bx_forum',

  1 => 'bx_forum',

  2 => 

  array (

   'menu_view' => true,

  ),

 ),

 'class' => 'TemplServiceMetatags',

)

Where's the difference to the settings in your image?
