QR code is stretched horizontally within its window #8944
Description
Overview
Resizing the QR code display window horizontally distorts the QR code itself, i.e. it's not square anymore.
Steps to Reproduce
- Select "TOTP / Show QR Code" from the context menu of an entry.
- Resize the window horizontally.
Expected Behavior
The QR code should always be square, centered and as large as possible within the limits of its allocated window are. (If the window is resized vertically, the program behaves correctly.)
Actual Behavior
The QR code is stretched horizontally, covering the whole width of the window. Scanning it with a smartphone camera will not work correctly.
