--- Comment #10 from BRULE Herman <alpha_one_...@first-world.info> --- Now the bug is years old... The problem was I think memory leak with plasma widget as network usage graph, cpu usage graph or other usage graph. Disable composing no change this. I had the problem opening just 1 window. But for KDE performance problem and stability, long time opened bug without solution I have switched to LXQt. I don't know if the bug remain valid. -- You are receiving this mail because: You are watching all bug changes.
