Hi!
I just updated to the latest Photoshop version (25.11.0), and my Legacy Healing Brush is creating jagged borders after brushing. This occurs when I'm working directly on the layer. If I try to use "current & below" on a blank layer, nothing happens—it's like I'm not brushing at all. This is happening with both large and low-resolution files.
I have already reset the Healing Brush tool and my preferences. The standard Healing Brush works fine; this issue only occurs with the legacy version.
Notes: This is happening in different files. All of them are set to 100% opacity and fill, with no holes in the layers, and all blend modes are set to "normal". The Healing Brush blend mode is also set to normal.
I'm running Photoshop on an M1 MBP with macOS Ventura.
