Changes in 8.4.1:

• Linux: Fixed a crash when "Show Profiles Toolbar" is enabled
• Mac: Fixed a scanning issue with Samsung scanners and Apple Driver
• Escl: Fixed an issue connecting to the wrong IP with mDNS responders

This beta update fixes several bugs reported in the previous build, and fixes compatibility for some effect plugins.

Changes since 5.2 Beta (build 9762):

• Fixed tooltips not displaying for the History and Layers windows
• Fixed compatibility for the Content Aware Fill effect plugin
• Fixed a bug that was causing the Dynamic Draw effect plugin’s output to have its alpha channel reset to opaque
• The mouse wheel can now be used to scroll menus other than Effects and Adjustments when they can’t completely fit onto the screen
• Optimized the performance of the canvas when at zoom levels >100% to use less memory bandwidth. This should reduce power usage on laptops.
• Wine: Improved text rendering quality and stability by using DWriteCore
• Wine: UI animations now work
