Render Thread Crash

The entire interface appears frozen or completely white, and the screen does not move at all, but it is actually operable (for example, resizing the window, mouse clicks respond, and the mouse pointer changes in different areas).

It is logged as System.Runtime.InteropServices.COMException: UCEERR_RENDERTHREADFAILURE or System.OutOfMemoryException: Insufficient memory to continue the execution of the program.
This issue was discovered in late December 2022, fixed in early April 2023, and the fix was released with Lyricify 4.1 in May 2023.

Cause

Section titled “Cause”

Unknown. No specific cause has been identified. It may be an issue with WPF itself, or it could be caused by the Media Session, and there are suspicions about the Windows 11 Mica material.
Due to the limited available memory of 32-bit applications, crashes are more likely to occur on certain systems.

Solution

Section titled “Solution”

Restart Lyricify.
Use the 64-bit version of Lyricify 4.1 or a later version.
