Corrected togling row count in the pager properties, however that action crashes kwin. - I can confirm other window decoration related crashes that seem already been reported. (nvidia-nuevo driver) thanks The crash can be reproduced every time. -- Backtrace: Application: KWin (kwin), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
