Linux 2026.3.0.5: Spanish accents lost and excessive RDP mouse-wheel scrolling

After upgrading RDM from 2026.2.2.2 to 2026.3.0.5, two problems appeared inside remote desktop sessions:

• Pressing the Spanish acute-accent key followed by a produces a instead of á.
• Each mouse-wheel notch scrolls approximately 10 lines, much farther than before.

Environment: CachyOS Linux, KDE Plasma on Wayland, RDM installed through the AUR package remote-desktop-manager. Both the local keyboard and RDM are configured for Spanish.

Steps to reproduce on the affected setup:
1. Upgrade RDM from 2026.2.2.2 to 2026.3.0.5 and open an RDP session.
2. In a text field in the remote session, press the acute-accent key followed by a.
3. In a scrollable remote application, turn the mouse wheel one notch at a time.

Expected: á is entered, and scrolling moves the normal amount per notch.
Actual: only a is entered, and scrolling moves approximately 10 lines per notch.

Downgrading only RDM to 2026.2.2.2 resolved both problems, without changing connection settings or downgrading system dependencies. The package versions were 2026.2.2.2-2 (working) and 2026.3.0.5-1 (affected).

Comparing the packages showed Avalonia changed from 11.3.17 to 12.1.2, while the bundled libDevolutionsRdp.so was byte-for-byte identical. This may help narrow the investigation, although it does not establish the root cause.

Please let me know whether this is a known regression and which release will contain a fix.

Hello,
The issue where pressing the Spanish acute-accent key followed by a produces a instead of á appears to be related to another reported keyboard issue. You can follow its progress here:

Regarding the excessive mouse-wheel scrolling, I have not been able to reproduce the issue on my end. Could you please provide the exact entry type you are using and, if relevant, the remote application in which the scrolling issue occurs?
I tested with Firefox and Notepad, but the scrolling behaved normally in both applications.
Best regards,

Hello,
I’m using an RDP entry (RDPConfigured). The excessive scrolling occurred throughout the remote desktop, across applications, rather than in one specific app.
Downgrading restored normal scrolling without changing any local or remote settings.
