Fractional scaling support does not work on Wayland (Linux) #308
Description
Description
Hi,
I'm experiencing an issue with fractional scaling when using Docker Desktop on Linux with Wayland. The UI becomes blurry or incorrectly scaled when using fractional display settings (e.g., 125%, 150%). The issue does not occur when using standard scaling values such as 100% or 200%.
Environment
| Item | Value |
|---|---|
| OS | Fedora 43 |
| Desktop Environment | Wayland |
| Display Resolution | 3840 x 2160 |
| Docker Desktop Version | 4.54.0 |
Screenshot
Reproduce
Steps to reproduce
- Launch Linux desktop session using Wayland.
- Set display scaling to a fractional value (e.g., 125%, 150%).
- Open Docker Desktop.
Expected behavior
Docker Desktop UI should scale properly and look sharp with fractional scaling values.
