Description: It might be the display setting of Windows 10, which is set to 150% as recommanded on my laptop, that causes the toolbar icons to be pixelated. Steps to Reproduce: 1. The display scaling is set to 150% in Windows 10 (that's recommended). 2. Open LibreOffice (Writer, Impress ...) Actual Results: The icons of the toolbar in each software (Writer, Impress ...) are pixelated. Expected Results: I expected that LibreOffice would better handle the esthetics of the interface and the icons in the toolbar. The software should have displayed the icons in a much better resolution. Reproducible: Always User Profile Reset: No OpenGL enabled: Yes Additional Info: Version : 6.3.5.2 (x64) Build ID : dd0751754f11728f69b42ee2af66670068624673 Threads CPU : 8; OS : Windows 10.0; UI Render : GL; VCL: win; Locale : fr-FR (fr_FR); Langue IHM : fr-FR Calc: CL
Thank you for reporting the bug. I have associated an additional keyword with the report to let the UX team evaluate this report.
Please identify the Icon theme in use, found from the Tools -> Options -> View 'Icons Style' drop list. Also, please post a screen clip of the "pixelated" icons. Clearing the user cache, C:\Users\<user name>\AppData\Roaming\LibreOffice will force rebuild of the scaled icon cache Also, let us know if setting the Windows UI to 125% scaling results in crisp icons.
Created attachment 159855 [details] First screenshot of the Libreoffice UI Hello, my icon style is Automatic (Colibre) After cleaning the cache like suggested, the problem isn't resolved. Setting the Windows UI to 125% scaling is better, but some issues persist. Some icons are not sharper.(see screenshot3.png in following post)

I can reproduce this. Seems like someone should look at the whole icon rendering, because beside this particular bug that manifests only with UI scaling > 100%, there also seems to be a bug at 100% scale that causes pixelation and excessively bold lines when using the SVG icons (the PNG icons are fine at 100%), probably using wrong rendering scale.
Tools > options > view allows also to use SVGs as icon themes. Scaling raster images will always end up in loss of quality (or time if the algorithm focus on quality).
The problem is SVG icons are broken too, even without scaling. Though disabling OpenGL rendering does fix that, so it might be a GPU driver issue, in my case AMD RX 570 with the latest drivers (20.4.2).
