   Is there an existing issue for this?

   Current behaviour

   On my Windows machine, the amount input field in the Send Coins dialog is extremely narrow (approximately 25 pixels wide). I can’t see the amount I’m entering, see screenshot:

   My Linux machine is not affected.

   Expected behaviour

   The amount field should be wide enough to display Bitcoin amounts clearly, as it was in v29.0.

   Steps to reproduce

   To reproduce

   1. Open Bitcoin Core v30.0 on Windows
   2. Go to Send tab
   3. Try to enter an amount - the input field is barely visible

   Relevant log output

   No response

   How did you obtain Bitcoin Core

   Pre-built binaries

   What version of Bitcoin Core are you using?

   v.30.0.0

   Operating system and version

   Win11 Pro 64bit

   Machine specifications

   Tested on: Dell XPS13 and HP Z2 mini G9 (both affected)

   • Display scaling: 100%
   • Screen resolution: 1920 x 1200 (laptop) and 1920×1080 (workstation)
   • Locale: German

   Can confirm on several Windows 11 24H2/25H2 machines with Bitcoin Core Master 5c5704e730796c6f31e2d7891bf6334674a04219. Built with Guix on Debian 12. For some reason, the field is fine if running the .Exe via Wine…

   The Custom Fee field and the Amount field in the Receive Tab are also affected. Resizing the window does not help.

   I tried to revert to a point it still worked, it seems that this is broken since the switch to Qt6.
