Can reproduce. This bug was briefly fixed in plasma 6.4 and it's beta, but returned in 6.4.1. Git commit 98bd108f093fce3677a8fd4fbf8521c4fc9e9d5d by Marcin Woźniak. Committed on 11/08/2025 at 10:46. Pushed by zamundaaa into branch 'master'. plugins/maximize: ensure all animations end on the same frame Otherwise WindowForceBlurRole is removed too early, causing blur to disappear for a frame.
