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
