Important detail: UWQHD (Ultra-Wide Quad High Definition) monitor with 3440 x 1440 pixel resolution. Possible troubleshooting steps (by Gemini): Since you have a modern setup (RTX 4060 + Ultrawide resolution), the disappearing borders in LibreOffice are likely not a hardware failure but a friction point between the software's rendering engine and hardware acceleration. ### 1. Conflict with Hardware Acceleration (Vulkan/OpenGL) LibreOffice tries to utilize your GPU to render the user interface. Sometimes, there is a mismatch between Nvidia drivers and LibreOffice's rendering engine, leading to "disappearing" UI elements. * **Solution:** Go to **Tools > Options > LibreOffice > View**. * Uncheck **Use Vulkan** or **Use hardware acceleration**. * Restart the program. This solves graphical glitches in about 90% of cases. ### 2. Windows Scaling and DPI Issues Since your resolution (3410x1358) suggests you aren't using 100% scaling (or Windows is "rounding" pixels), LibreOffice might miscalculate the position of thin lines. If a border falls "between" two physical pixels due to scaling, the program may fail to draw it. * **Solution:** Right-click the LibreOffice shortcut > **Properties** > **Compatibility** > **Change high DPI settings**. * Check **Override high DPI scaling behavior** and select **System** from the drop-down menu. ### 3. Nvidia Control Panel Settings (Anti-aliasing) Sometimes, global anti-aliasing settings in the Nvidia Control Panel can blur or "erase" thin, single-pixel lines in productivity apps. * **Solution:** Open the **Nvidia Control Panel**, go to **Manage 3D Settings**, and ensure that "Antialiasing - Mode" is not set to "Override any application setting" for LibreOffice. ### 4. View Settings within the App Sometimes the simplest explanation is the right one: * Check **View > Table Boundaries** (or **Text Boundaries**). * If the issue only occurs at specific zoom levels (e.g., 95% or 105%), try using a fixed **100%** or **Page Width** zoom. Ultrawide monitors often trigger rendering artifacts at "odd" zoom percentages. **Pro Tip:** Since the RTX 4060 is a very recent card, make sure you are using the **LibreOffice "Fresh"** version (the latest release) rather than the "Still" (older, stable) version, as it contains more fixes for modern hardware. --- **Follow-up:** Are you using a DisplayPort or HDMI cable, and do you have G-Sync/FreeSync enabled on your monitor? -- You are receiving this mail because: You are the assignee for the bug.
