Change Log

Changes since 5.2 Alpha (build 9641):

• Fixed an issue when drawing at the edge of the canvas viewport that would cause it to freeze and then jump all the way to the far edge of the canvas
• Fixed an issue when drawing a selection using the intersect combine mode that would make the selection disappear and cause other weird issues with history (undo/redo).
• Fixed the Move Selected Pixels tool setting color values to 0 for transparent pixels when not necessary (just moving without scaling/rotation, nearest neighbor sampling, etc.). Bug was reported here by @frio.
• Fixed clipboard images accessed by plugins not always having a non-null ColorContext property. This property can still be null in some cases (e.g. alpha-only pixel formats). Reported here by @_koh_.
• Optimized the compositing code for the Move Selected Pixels tool. The improvement is most noticeable on CPUs with AVX2 (not AVX512) which are not already bottlenecked by the GPU’s rendering.
• Fixed a rare crash that could happen while switching tools while also changing the color
