Brush size adjustment depends on view angle

[AdamF]

Affinity Photo 2.1.1 (Latest version as of July 11 2023)
MacBook Pro 15-inch, 2019
macOS 13.4.1 (22F82)

Repro steps:
* File > New > Web XGA
* Select the paint brush tool and a basic round brush
* Create a pixel layer
* Hold down ctrl and option and click and drag left and right. Brush changes size.
* View > Rotate Left, repeat until view is rotated 90 degrees
* Hold down ctrl and option and click and drag left and right. Brush changes hardness.

Expected result: Left/right movement always adjusts brush size, independent of view rotation

Actual result: Adjustment depends on view rotation

Notes
* Reproduces regardless of hardware: built-in trackpad, mouse, wacom tablet, with and without external monitor
* Reproduces with hardware acceleration on and off (tried both)
* Also reproduces on iPad (using ctrl and option on command controller) (version 2.1.1.1847)

Probably this known issue: https://forum.affinity.serif.com/index.php?/search/&tags=AFP-2660

I agree, sounds like the same issue. Some clarifications that might not be apparent from the other issues with that tag:

• This is a bug, not a feature request
• It affects the latest version of Affinity Photo on both macOS and iOS
• It reproduces reliably without any unusual hardware
• It is a serious problem for painters, not a minor inconvenience

Hi Adam,

Walt is correct this is a known bug, we should hopefully have this fixed in a future update.

Thanks

Great, glad to hear it! I just realized that there is a related problem: the rotation of the brush itself also depends on the view angle (e.g. if I use one of the calligraphic pens). Is that also on the developers' radar?
