First, please check the graphics card driver of Dell notebook. Will the graphics card driver cause software running problems? It is suggested to install "Driver Wizard" or "Driver Life" to update your notebook graphics card driver to the latest Microsoft digital signature version. Restart the computer after installation and try again.
Second, upgrade the faulty software. Upgrade both Storm Video and QQ, and then see if there will be ghosting. If it is still a ghost, it is recommended to change the player. If you need a player with play online function, switch to "Thunder Watch" or "QQ Video" (the latest version 9. 1 is made by Tencent itself, so there should be no incompatibility).
Thirdly, if you don't need the play online function and only use the local playback function of Storm Video, it is recommended to install KMPLAYER, which is very practical. You can choose to speed up the playback when playing, saving a lot of time! I hope my answer can help you, and I hope my answer can be adopted. Thank you!
