Lukas <luke-m...@online.de> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |luke-m...@online.de --- Comment #1 from Lukas <luke-m...@online.de> --- I am experiencing similar issues with kwin_x11 and plasmashell. Both processes constantly eat up about 20% of CPU time. kwin_x11 CPU usage returns back to normal once I kill plasmashell. The issue arises during regular operation without secondary monitor although I have not testet it with a dock. An strace of plasmashell showed that it was pretty busy with various DRM systemcalls to the i915 Intel graphics driver although I have no idea whether this is in any way related to the issue. The issue first occurred after a system upgrade which comprised the following changes: Qt 5.8 -> Qt 5.9 kwin 5.10.1 -> 5.10.2 plasma-workspace 5.10.1 -> 5.10.2 I am running an Arch Linux installation on a Thinkpad T470: Intel Core i5-7200u Intel HD Graphics 620 A colleague with a Thinkpad X1 (also Intel CPU and Graphics) experiences the same issue. Please let me know if I can provide you with further information. -- You are receiving this mail because: You are watching all bug changes.
