Missing Title Bar when publishing to Arm64 devices ( Raspberry Pi )

[speed2048]

Current behavior

When running the standard application from dotnet new unoapp -preset=blank -o test dotnet command and publish using linux-arm64. Deployed to raspberry pi ( bookworm / aarch64 ) the Title bar does not appear as well as the minimized, maximized and close buttons. This does occur for mac, linux-64 or windows platforms. Not sure if this would work on 32 bit arm platform as I do not have one.

Expected behavior

Windows title and min, max, close icons should be there.

Thanks for the report. We're not able to reproduce this issue on a Raspberry Pi.

A few things:

• Could you provide the full version of your distribution?
• Are you able to test on a separate Linux system?
• Could you provide the output of the terminal?

Thanks!

Hi Jérôme,
Here is the infomation from the raspberry pi.

uname -a
Linux raspberrypi-5-002 6.6.74-v8-16k+ #1844 SMP PREEMPT Mon Jan 27 11:43:09 GMT 2025 aarch64 GNU/Linux

lsb_release -a
LSB modules are available.
Distributor ID: Debian
Description: Debian GNU/Linux 12 (bookworm)
Release: 12
Codename: bookworm

Running wayland X windows system.

On Windows 11 24h2 PC

UNO.Sdk 5.6.30
VS 2022 V13.0
Dotnet sdk 9.0.2

It does correctly have the title bar and min/max/close buttons when I run this on a linux-x64 platform ( ubuntu 24.04 ) platform.

I also built the application on the pi and with the same results ( however there is an error on the console:
fail: Uno.UI.HotDesign.Client.Logic.DevServer.RemoteControlService[0]
DevServer isn't able to connect

Regards,
Bob
