Issue Details

  • I have created a Screen in FlexLogger, which consists of several graphs. The graphs appear frozen and do not update until I manually change tabs and go back to the Screen. How can I fix this?
  • None of my FlexLogger charts are updating continuously. The x-axis appears to update but all values on the y-axis appear stuck. Why is this happening?
  • Graph indicators on my FlexLogger screen are not updating regularly. Other indicators are fine, but my graphs look as if they have taken a snapshot and frozen.

Solution

This problem can be caused by several factors. To resolve it, follow the steps below:
  1. Check for graphics driver updates. It may be that the driver (specifically Hardware Acceleration features) is preventing data from being displayed correctly.
    • Refer to your PC manufacturer's website to find the correct graphics driver.
    • Run an update to ensure that the latest driver version is installed.
    • Ensure that you have performed update on all graphic cards installed within the system to the latest version.
    • Restart FlexLogger.
  2. Verify that the operating system is compatible with the installed version of FlexLogger.
    • Refer to the FlexLogger download page and expand the Supported OS section to view a list of compatible operating systems.
    • Using an unsupported operating system can result in unexpected behaviour.
  3. Ensure that the PC's CPU usage is at normal levels.
    1. Open Task Manager and navigate to the Processes tab.
    2. Scroll through the list of processes to identify FlexLogger.
    3. Check the CPU usage to ensure that this is not causing FlexLogger to freeze. Note: normal CPU usage varies depending on the active processes. Idle Windows 10 PCs should use around 2 - 4% of the CPU. Alternatively, browsing the internet with multiple tabs can result in 50% CPU usage. If the CPU usage reaches 100%, this indicates that a process is trying to use resources that are unavailable, which can result in applications freezing or crashing.
    4. To reduce CPU usage, consider ending processes that do not need to run and restarting the PC.
  4. Try reinstalling FlexLogger to remove the possibility of a corrupt software installation.

If the issue still persists, please raise technical support and share screenshots of the Device Manager and the PC manufacturer’s website that clearly indicate the driver's name and versions.
