Not reproduced on Linux: Version: 24.2.3.2 (X86_64) / LibreOffice Community Build ID: 433d9c2ded56988e8a90e6b2e771ee4e6a5ab2ba CPU threads: 8; OS: Linux 6.5; UI render: default; VCL: gtk3 Locale: en-AU (en_AU.UTF-8); UI: en-US Calc: threaded Can you please copy and paste here your full version information from LibreOffice > About? There's a button to copy it. Does changing the Skia settings in "LibreOffice > Preferences > LibreOffice > View" change anything? Wondering if it has to do with 12fd870113a663dde5ceb38c61f1986a34095d0e like bug 160690.
