Description: Without modification of the appearanc, the page border was sometimes invisible, i.e. white/missing page border on the white application color (see on the attached screenshot). A possible problem with the automatic settings of the appearance? Solution or workaround: Enabling Shadows [x] Show in documents in Customizations part of Tools->Options->LibreOffice->Appearance (which was disabled interestingly). Steps to Reproduce: Open a document with multiple pages. Actual Results: Sometimes missing page border. Expected Results: Visible page border. Reproducible: Always User Profile Reset: No Additional Info: Video card: Nvidia Geforce RTX4060

@László Kovács: thanks for the bug report! 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?
More information from the bug reporter: – The same problem with the same machine, but with different monitors – Analysis with chatGPT, checking skia.log: * GPU acceleration is enabled with Skia (but hardware acceleration is grayed out on the UI) * Render Method: Vulkan * RTX 4060 is recognized * driver is OK
Thank you for reporting the bug. I can not reproduce the bug in Version: 26.2.3.2 (X86_64) Build ID: 70e089b17412e4cb7773e41413306b17a2328c34 CPU threads: 16; OS: Windows 11 X86_64 (build 26200); UI render: Skia/Vulkan; VCL: win Locale: en-US (en_US); UI: en-US Calc: CL threaded
Hi László, I don't see an issue with a nVidia RTX 4060 TI on a 4K display, MS DWM seems to handle the AppFrame scaling of the LO UI with no issue either skia Vulkan of skia raster framing. I do see some issues as I change between os/DE DWM color scheme if LO appearance is in either Light or Dark instead of Automatic. So I tend to just leave it in automatic. No issue is I check enabled LO appearance themes and select a light or dark theme appropriate to the os/DE DWM color scheme in use. I tend not to try to mix a light appearance theme with a dark os/DE color scheme or vice-versa. Could your visual glitches on the ultra-widescreen be the skia Vulkan driver? What nVidia driver are you running? You can identify with the 'vulkaninfo' report from cmd window, or a run of 'msinfo32'. For example, I get the below from vulkaninfo for my working daily driver. Though it looks like I'm a bit behind as they've released 610.47, 596.49 this month, and a later 595.97 update.
