What's new in Paint.NET 4.0.17

July 20, 2017
  • Added: "Fluid mouse input" option in Settings -> UI -> Troubleshooting. If you see major glitches while drawing, try disabling this.
  • Improved: Default brush size, font size, and corner radius size now scales with major DPI scaling levels (brush size of 2 at 100% scaling, brush size of 4 at 200% scaling, etc.)
  • Improved: Default image size now scales with major DPI scaling levels (800x600 at 100%, 1600x1200 at 200%, etc.)
  • Improved performance and drawing latency by removing explicit calls to System.GC.Collect() except when low memory conditions are encountered
  • Improved performance by greatly reducing object allocation amplification by reducing the concurrency level when using ConcurrentDictionary, and by removing WeakReference allocations in favor of direct GCHandle usage
  • Improved: Performance and battery usage by ensuring animations always run at the monitor's actual refresh rate
  • Improved (reduced) CPU usage when moving the mouse around the canvas
  • Removed: "Hold Ctrl to hide handle" from the Text tool because it was not useful and caused lots of confusion
  • Fixed: Various high-DPI fixes, including horrible looking mouse cursors caused by a bug in the latest .NET WinForms update
  • Fixed: Gradient tool no longer applies dithering "outside" of the gradient (in areas that should have a solid color)
  • Fixed: Very slow performance opening the Effects menu when lots of plugins are installed after installing the Windows 10 Creators Update
  • Fixed: When cropping and then performing an undo, the scroll position was totally wrong
  • Fixed a rendering glitch in the Save Configuration dialog (it would "wiggle")
  • Fixed: At certain brush sizes, the brush indicator on the canvas had a visual glitch in it due to a bug in Direct2D
  • Fixed: Text tool buttons for Bold, Italics, Underline were not localized for a few languages
  • Fixed a rare crash in the taskbar thumbnails
  • Fixed: Drawing with an aliased brush and opaque color (alpha=255) sometimes resulted in non-opaque pixels due to a bug in Direct2D's ID2D1RenderTarget::FillOpacityMask
  • Fixed: "Olden" effect should no longer cause crashes (it still has some rendering artifacts due to its multithreading problems, however)
  • New: Portable mode can be enabled via a setting in the .exe.config, which will redirect app settings into a local JSON file (see blog/forum post for details)
