For the Intel® graphics 520 controller there is a new driver available, it is version 4590, please try to install that driver:
Also you can try driver 4552:
I was looking in Dell’s web site for graphics drivers, but there are many different models of Vostro, could you please provide the specific model of the one you are using?
Please let me know the results of trying the drivers above.
Any further questions, please let me know.
Thanks for help! I just installed the newest drivers 4590 and now graphics card works perfect. Funny because I frequently checked Intel website for the newest drivers. Recently I installed a driver version 4589 but cursors were sharp as on previous ones. It seems that only the newest - driver 4590 solves this strange problem( I guess AERO display bug? ).
