Windows 7: Screen flicker
Answer ID 4612   |   Last Review Date 12/18/2018

We just upgraded from XP to Windows 7. Why does the CX application flicker?

Environment:

All supported versions

Resolution:

The screen flickering with Windows 7 and the CX application is a Windows 7 design limitation based on the kernel stack size. Once the hierarchy of windows exceeds a certain size, screen flickering and flickering of the CX application can be seen.

This screen flicker is more prevalent in the 64-bit version of Windows 7.

Some things you can do to reduce this flickering are:

Ensure that your video card is compatible with Windows 7 and that the newest drivers for the video card are installed. To check your video card, follow this link:

Also, ensure that your BIOS, Chipset, and NIC drivers are up to date.

 

Consider redesigning your workspace and or reducing the number of nested tabs within the application.
