I made a little app to help clean image retention

Hi, I got some image retention on my OLED the other day, and I couldn't find any app that would help me clean a specific area (the windows taskbar), so I made a little Java app, and I'm sharing it with you.

  • It opens a rectangle that draws random pixels on the area.
  • You can drag it with your mouse.
  • You can close it via the console or by pressing alt+f4

java -jar oledhelper.jar <width> <height>
Example, for an area of 640x480 pixels:
java -jar oledhelper.jar 640 480

For a full 4K resolution, you'll need 2gb of ram.

It's good enough for me, but I can tweak it if someone asks for something more specific.
