Samsung Galaxy Z Fold 5 Screen Flickers Only When Charging Fast, Not Slow Charging

I've been loving my new Galaxy Z Fold 5, but recently I noticed something weird. When I plug it in with the official fast charger (45W), the screen flickers intermittently, especially when the device is off or in standby. However, if I switch to slow charging with a regular 15W charger, the flickering stops completely. I've tried rebooting, clearing cache, and even a factory reset, but no luck. The flickering only happens during charging, never when unplugged. I'm worried this might be a hardware issue with the charging circuit or screen, but I haven't found anyone else reporting the same problem online. Has anyone experienced this with foldables or similar devices? Could it be related to power delivery or a software glitch tied to fast charging? Also, is it safe to keep using slow charging as a workaround, or will that damage the battery over time? Any insights or similar experiences would be super helpful!
