This update adds the ability to configure the Rounded Rectangle shape’s corner size. It also fixes issues with scrolling and panning, effect rendering performance, high DPI, and a rare system hang caused by WPF.
As usual, you can download the update directly from the website, or you can use the built-in updater via Settings –> Updates –> Check Now.
Change log:
- New: Rounded Rectangle’s corner size ("radius") is now configurable
- New: Overscroll can now be disabled from within Settings
- Fixed: The Zoom tool was broken in 4.0.10
- Fixed: Auto scroll will no longer engage overscroll. This prevents the image from shooting off in all directions when drawing on it or when making a selection.
- Fixed: Panning with the middle mouse button would sometimes be "sticky", as reported at http://forums.getpaint.net/index.php?/topic/110131-dragging-with-the-mouse-wheel-is-sticky/
- Fixed: Effect rendering performance had significantly regressed in 4.0.10, by as much as 50%, on Intel CPUs with HyperThreading. http://forums.getpaint.net/index.php?/topic/110090-paintnet-run-significantly-slower-on-windows-10-compared-to-windows-7/
- Fixed: Selecting the entire image and then using Zoom to Selection or the Zoom Tool would align the image in an awkward manner
- Fixed: In rare cases, Settings -> Plugin Errors was hanging the whole system (bug in WPF?). This UI is now implemented in WinForms instead of WPF. http://forums.getpaint.net/index.php?/topic/110002-plugin-error-screen-complete-pc-freezelockout/
- Fixed some more high-DPI issues, especially when using multiple monitors with mixed DPI, or when using Remote Desktop
Enjoy!

Great update, you guys are champs!
For the next update, could you get the effects and adjustments to use the GPU. And could you add shortcut editing?
Amazing update. Keep up the good work!
Thanks for the update, Rick 🙂
Excellent!
Would it be possible to include a feature to reset overscroll with a hotkey?
For example by also resetting overscroll when resetting zoom with View / Actual Size or pressing CTRL + 0?
It is possible today to move selected pixels or the selection itself using the cursor keys (and CTRL+cursor keys for larger movement).
Would it be possible to add a feature that would allow us to adjust the selection size with SHIFT + cursor keys (and CTRL+SHIFT+cursor keys for larger movement)?
