Go to Applications Management in your device settings. Clear your data and cache (this will require you to sign in to VDR again).
If the problem persists, please uninstall and reinstall the application. Please note that reinstalling VDR will not cause loss of data.
As VDR is a 2D, web-based game, it is unlikely that will cause direct issues with your device. It is no different from browsing a graphics-heavy web page in your browser.
Please research your device's specifications versus any other installed apps thoroughly to ensure that other programs are not interfering with the use of your device.
