--- Comment #2 from Tonurics <tonur...@gmail.com> --- Created attachment 131763 --> https://bugs.kde.org/attachment.cgi?id=131763&action=edit Folder panel with sub-folders that can't expand. I've put red squares where I see arrows flashing. I would guess they start flashing at a rate of about ~12 times a second [creating a faux transparency effect like in an old video game]. Either because system load is building, or the function checking for sub-folders is self-referencing: over time the arrows appear on screen for longer periods of time. This coincides with Dolphin using 100%. -- You are receiving this mail because: You are watching all bug changes.
