SimVision 25.03-s006: Toolbar icons nearly transparent over RDP on AlmaLinux 9.5

We are experiencing a rendering issue with SimVision 25.03-s006 on AlmaLinux 9.5 when accessing the system through an RDP session. The application starts and operates normally, but the toolbar icons are rendered almost transparent or heavily washed out, making them difficult to recognize. Only the toolbar icons are affected; all other user interface elements, including menus, dialogs, text, waveforms, and the rest of the application, are displayed correctly. The issue is fully reproducible and occurs every time SimVision is started via RDP. The RDP client is Remmina 1.4.25 using FreeRDP 2.6.1. Since only the icons are affected while the rest of the GUI is rendered correctly, the problem appears to be related to icon alpha blending or Qt icon rendering. We would like to know whether this is a known issue with SimVision 25.03-s006 in an RDP/xrdp environment on RHEL/AlmaLinux 9, and whether a workaround or patch is available.
