Question

My Dell XPS 13 9343 2015 with Windows 10 sometimes does this when I open it. But after I close it and open it again it works just fine. Or sometimes it happens if I wake it up instantly after he goes to sleep mode image

Could be a driver issue, but those lines to me could indicate a hardware fault. Run the LCD Built-in Self-Test.

update: i installed the dell support service and updated the drivers, now it only happens sometimes when I restart my laptop, it doesn't affect performance, doesn't happen when the laptop is on, i think reinstalling windows will solve it, but it's not irritating and happens rarely.
