When "Current Application Control" applet is active it consume X process' shared memory (through plasma-desktop process). Every time I switch windows applet changes contents and leaks memory. So Xorg shared memory is increasing and after a few hours X share memory is cca 500MB high and keep increasing. Cleanup can be made by killing plasma-desktop and starting it again. Reproducible: Always Steps to Reproduce: 1. Add "Current Application Control" applet to the plasma panel. 2. Open KSysGuard or something for observing process memory and shared memory. 3. Switch windows (alt+tab or clicking on taskbar entries) multiple times and observe the X process shared memory increasing. 4. Remove the applet from the panel and the memory increasing while switching windows should be stopped. 5. # killall plasma-desktop 6. # kstart plasma-desktop 7. X process shared memory should be at normal numbers again. Actual Results: X process shared memory is irreversibly increased each time windows are switched. Expected Results: X process shared memory should not increase each time windows are switched. This bug occures in KDE version 4.11 and 4.10 as well. I don't know of any earlier versions.
Hello! This bug report was filed for KDE Plasma 4, which reached end-of-support status in August 2015. KDE Plasma 5's desktop shell has been almost completely rewritten for better performance and usability, so it is likely that this bug is already resolved in Plasma 5. Accordingly, we hope you understand why we must close this bug report. If the issue described here is still present in KDE Plasma 5.12 or later, please feel free to open a new ticket in the "plasmashell" product after reading https://community.kde.org/Get_Involved/Bug_Reporting If you would like to get involved in KDE's bug triaging effort so that future mass bug closes like this are less likely, please read https://community.kde.org/Get_Involved#Bug_Triaging Thanks for your understanding!
