I'm running Lightroom 6.14 (permanent license version) set to English language on a German Windows 7 system with German keyboard.
Adjusting the brush size or feather size for local adjustments doesn't work. The brush and some buttons and texts on the right panel flicker, but no changes happen.
On a German keyboard the corresponding keyboard shortcut for typing '[' and ']' are ALT+8 and ALT+9. ALT however also alternates the functions of some buttons as seen in the screen capture above. For the short demo I'm tapping on pads of my MIDI controller assigned to "brush size +", "brush size -", "brush feather +", and "brush feather -".
When my keyboard is switched to US English it works fine. Is there a way to fix it so that I can work with the German keyboard setting?
