Text (Liberation Sans) blurred in Calc after update

[alfons11]

In Calc, I use Liberation Sans (10 pt) for values of cells.

There seems to be a difference between then current version of LibreOffice and older versions (f.e. 24.2.5.2 - July 2024) I cannot understand.
After one of the last updates (as I didn´t updated some time, I cannot tell the number, but I tried to install f.e. 24.2.5.2 and here all works fine), my text looks different: it is a bit blurred.

In the attachement, there is an example of an .ods file and also a picture with screenshots that show the difference.

How can I prevent these unwanted changes?

Thank you.

How can I prevent these unwanted changes?

First steps to take before submitting a bug

Have a look there at:

• Computation-related issues in Calc (OpenCL)
• Graphics-related issues ( Skia )
• Fonts issues
• Rendering issues specific to Linux

I tried to open it on another device (another Windows version etc.) with updated LibreOffice, and it works fine (not on my main device,here the problem persists). Please, what should I try on my main device?

Things that can affect blurriness of text in Windows

• Start menu > Settings > System > Display > Scale
• Start menu > Settings > System > Display > Resolution
• Font smoothing
  1. Press the Win+R keys to open Run, type SystemPropertiesPerformance.exe into Run, and click/tap on OK to directly open to the Visual Effects tab in Performance Options
  2. Check (enable - default) or uncheck (disable) Smooth edges of screen fonts for what you want, and click/tap on OK
• The font you are using might work better or worse than another font for different resolution or font smoothing

Things that can affect blurriness of fonts in LibreOffice

• Zoom of document (yours is 90%, it should look sharper at 100% or a multiple of native screen resolution). If display scale has been set to 125% in Windows, then zoom of 80% or 160% is likely to be sharper than 100%
• Possibly Tools > Options > LibreOffice > View > Use Anti-aliasing (requires restart)

Thank you! Font smoothing (setting in SystemPropertiesPerformance.exe) was the solution.
