as a workaround, you can try SAL_USE_VCLPLUGIN=kf5 libreoffice26.2 or SAL_USE_VCLPLUGIN=kf6 libreoffice26.2 works for me with ubuntu 24.04 / X11, although not the same version of LO Version: 25.8.4.0.0+ (X86_64) / LibreOffice Community Build ID: 12c639145df4450f7cba3abe0628ad016071a3a5 CPU threads: 8; OS: Linux 6.14; UI render: default; VCL: x11 Locale: en-US (en_US.UTF-8); UI: en-US Calc: threaded
Since years, I use the generic toolkit because gtk is too buggy when using Base forms. This happens with LO 26.2 for the first time.
