This is a small update that contains fixes for some bugs and that were discovered in 5.1, as well as a new Fill option in the Image -> Canvas Size dialog. It also has workarounds for some bugs in Sentinel One (antivirus) that were causing crashes in the installer and hangs during app startup.

Get the Update

There are two releases of Paint.NET:

• Microsoft Store release (recommended)
  • You can purchase it here. This helps fund development and is an alternative or supplement to sending in a donation. In addition, updates happen automatically in the background when you’re not using the app.
  • If you already have it installed, the update should happen automatically once Microsoft certifies the update, usually within the next day or so. To get the update immediately (once it’s certified), you can follow the instructions listed here.
• Classic Desktop release
  • Download the installer from the website. This is the recommended download if you don’t have Paint.NET installed. It can also be used to update the app.
  • If you already have it installed, you should be offered the update automatically within the next few days, but you can also get it immediately by going to ⚙ Settings -> Updates -> Check Now.
  • Offline Installers and Portable ZIPs are available over on GitHub.

• Changed Edit->Cut and Edit->Crop to Selection to completely zero out pixels outside of the selected area, which could otherwise be a privacy issue.

• Worked around a hang at app startup if Sentinel One antivirus.
• Fixed many cases of screen blanking, rendering glitches, and crashes on systems with certain NVIDIA GeForce GPUs, and certain displays with support for overlays and/or VRR (FreeSync, GSYNC). This appears to be a bug in NVIDIA’s driver.
