Maybe I assumed incorrelctly what haplened, I can’t find a photo of it, it happened years ago.

Basically I wanted to back up a pretty old laptop with win7. I booted up an arch linix live usb. Started cp-ing from internal to external driver without default NTFS driver. Afer a few minites i noticed some random colored pixels creeping in from the top right side of the monitor. Most of the screen should have been black because it was displaying the terminal. By the time it finished there were multiple different lenght rows with random bright colors. After restarting on win7 these presisted. During a few days the lined got shorter, but never disapeared even after years.

No idea how this happened

once i was copying files from a windows install on ntfs fs to an external ntfs drive on an old laptop. somehow the system got so hot, it permanently damaged the GPU, and left marks on the display
