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:
https://forum.devolutions.net/topics/56258/rdm-on-debian-13-wrong-keyboard-layout
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.

Hello,
I tried to reproduce the scrolling issue using three different Linux distributions and multiple RDP sessions connecting to both Linux and Windows hosts, but the scrolling behaved normally in every test.
Could you please create a new RDP entry from scratch and confirm whether the excessive scrolling is still present with the new entry? This will help us determine whether the issue is related to the existing entry’s configuration.

Hello,
After creating a new entry, it behaves the same way. Also, a new thing I noticed, when hovering on windows borders or text fields, the cursor do not change the icon as it does normally with the previous working version.

Also, the cursor style stays the same as linux host, instead of showing the remote desktop destination mouse.

Hello,
Thank you for the detailed report and for testing the downgrade.
Your comparison between the two packages is very helpful.
Yes, this is a regression in RDM Linux 2026.3.0.5.
Version 2026.3 ships a new Linux interface, and it changed how keyboard and mouse input is sent to RDP sessions.
Our QA team has already reproduced related keyboard problems in RDP sessions on this version, and they are tracked by our development team.
The lost Spanish accents fit in that same group of issues.
We have not been able to reproduce the larger scroll step per wheel notch on our side yet.
We do not have a release date for the fix yet.
For now, the best workaround is to stay on RDM Linux 2026.2.2.2, as you already did.
Your entries and settings are kept when you change versions, but we suggest a backup of your data source first.
If you use the AUR package, you can also hold the package version so that it is not updated by accident.
We will update you as soon as a build with the fix is available.
Best regards,

Hello,

Thank you for being so patient!

If possible, could you update your RDM Linux to the latest version (2026.3.1.1) and see if the problem persists? This version should resolve your issue.

Latest Version: Download RDM

If the problem persists after the update, please let us know so we can inform our development team.

Best regards,
