Designer 2.1.0 - Opacity Dropdown Bug

Recommended Posts

Hello, I believe I have found a bug involving the opacity dropdown menu in Affinity Designer 2.1.0.

  • When using the opacity slider, things work as expected.
  • When using the dropdown menu, however, the opacity percentage changes, but it has no effect on the actual object selected.
  • When typing a value in for opacity, it usually works, but not always.

This has been demonstrated in the attached video. I also included the file I used in the video, although this happens on all files both old and new.


System Information:

  • Bug occurs on Affinity Designer 2.1.0. It did not occur on previous versions.
  • Windows 10, Version 21H2, Build 19044.2965
  • Processor: AMD Ryzen 7 5800X
  • GPU: AMD Radeon RX 6700 XT
  • 64GB RAM
  • Bug happens with hardware acceleration both on and off
  • No unusual devices/drivers involved

Same here, slider works fine, entering value with keyboard works, but drop down does not update the opacity of the object. If you click on the small circle on the slider opacity is then adjusted.

But shortcuts (1 -2 -3 ... ) work fine

I can replicate this in Designer 2.1 on Windows 10.

Dragging the slider with the mouse changes the opacity and sets the value in the field accordingly;
Entering a value in the field changes the opacity and the slider is moved accordingly;
Selecting an opacity from the drop-down with the mouse moves the slider accordingly but does not change the opacity.

Note: The same issue is also evident with the Noise functionality in the same Panel.

I also just noticed that scrolling the mouse wheel over the percentage to change it in single-digit increments also no longer works.
