August 2026 RDP font display glitch

In the last days, we have received two independent reports of font display problems in our MS Access based application. The symptoms are as follows:

• Some labels or text boxes are shown in a legacy system font instead of the font specified in the control (Segoe UI). Also, the label/text box is shown with a white background instead of transparent.
• Moving the Access window "fixes" the glitch.
• It happens at seemingly random places in our application at seemingly random times.

Both reports have in common that the Access application is running inside an RDP session. In report 1, a work-from-home user used Remote Desktop to connect to their office Windows 11 PC, and, in report 2, a user executed the application on a Windows Terminal Server.

Here are a few screenshots to illustrate the problem. The left side is the glitch, the right side is how it is supposed to look. The first row shows labels, the second row text boxes in a continuous subform.

Report 1 is 16.0.20228.20186, 32 bit, M365 SAEC.

Report 2 is 16.0.14334.20848, 32 bit, Office 2021 LTSC.

Is this a known issue, or shall we continue to collect data about this glitch? Unfortunately, we haven't found a reliable way to reproduce it, so our ability to test it with different versions is limited.
