4. Problematic Apps
Certain apps — especially screen recorders, overlay tools, or customization software — can trigger flickering.
5. Hardware Acceleration Conflicts
Modern apps use GPU acceleration, which may clash with some systems.
6. Loose Display Connection (Desktop Users)
HDMI or DisplayPort cable issues can also cause random flickering.
