trouble when rotating screen

[VinceVg]

Hello,
When I read comics lying on the bed , I rotate my screen (with CTRL + ALT + Left Arrow) . But it becomes impossible to use the automatic movement :
Right 1 screen , 1 screen right , one screen right ...
Left side and down 1 screen , 1 screen right , right 1 screen , 1 screen right ...
Left side and down 1 screen , 1 screen right , right 1 screen , 1 screen right ...
and so on .
Can you fix this
Thank you
