 [Fixed Bugs and Problems]

• Fixed a bug where if the app is closed immediately after deleting layer, the playback process of the artwork becomes wrong.
• Fixed a bug where the Layer thumbnail of the current layer is displayed blurring after you draw with "Outline" or "Watercolor" brushes to a relatively small canvas.
• Fixed a bug where brush lines may not be reflected on the canvas under memory shortage.
• Fixed a bug where the line break at the end of a vertical Text is ignored. If you want to correct an existing Text with this problem, please re-edit the text or modify the style.
• Fixed a bug of "Glow (Outer)" filter where if the "Crystal Glow" is OFF then it fills the layer with some thin color.
• Fixed a bug where "Jitter thickness" of brushes does not work if "Scatter" is OFF and "Jitter Thickness per Particle" is ON.
• Fixed a bug where at almost all points of a brush line the thickness is unintentionally the same to the value of "Thickness of Start" under some conditions on brushes and stabilizer settings (that is, "Watercolor" brushes or Smudge/Blur tools such that "Force Fade Out" is ON or Jitter Color is "Endpoint", and the method of stabilization is "Real Time").
• (Android version) Fixed a bug where on some devices the blending mode "Behind Pattern" of brushes has no effect and some brushes such as "Three Strand Braid" or "Four Strand Braid" don't work properly.
• (Android version) Fixed a bug where on some devices the shadow drawn by the Bevel filter is too dark.
• (Android version) Fixed a bug where on some devices a menu which should be opened via "⋯" button in My Gallery doesn't displayed.
• (iOS/iPadOS version) Fixed a bug on devices supporting 3D touch where the pressure by 3D touch is reflected at the end of brush lines ten times stronger than intended under some conditions on brushes and stabilizer settings (that is, "Watercolor" brushes or Smudge/Blur tools such that "Force Fade Out" is ON or Jitter Color is "Endpoint", and the method of stabilization is "Real Time" and "Stabilizer" is OFF).
• (iOS/iPadOS version) Fixed a bug where the line break at the end of a horizontal Text is ignored.
• (iOS/iPadOS free version) Fixed a bug where some ads causes the app crash.
