--- Comment #36 from Matt Whitlock <k...@mattwhitlock.name> --- Created attachment 110735 --> https://bugs.kde.org/attachment.cgi?id=110735&action=edit time-series chart demonstrating plasmashell memory leak Do we need to open a new bug report for the slideshow wallpaper issue? I am running Qt 5.9.4 and Plasma 5.12.1 now, and it most definitely is still an issue. Please see the attached chart, which visualizes the output of... • free | grep '^Mem:' • grep '^VmRSS:' /proc/"$(pgrep plasmashell)"/status ...with samples taken at 1-second intervals while manipulating plasmashell. Particularly noteworthy is that the actual plasmashell process's VmRSS hardly changed the whole time. The system is evidently not accounting the memory usage to the plasmashell process. Nevertheless, given enough time, plasmashell brings the system to its knees. (I actually had to use AltGr+SysRq+F to manually invoke the OOM killer just so I could terminate plasmashell, as my session had become unresponsive.) I would reasonably expect to see the gradually increasing "Buff/Cache" line and the gradually decreasing "Free" line, as the block cache should be caching the JPEG files as they are loaded from disk. (This is no problem, although frankly plasmashell ought to be calling posix_fadvise(2) with POSIX_FADV_DONTNEED on these files.) What I would NOT expect to see is the "Used" line increasing and the "Available" line decreasing. This suggests that memory is being consumed by something other than the block cache. My best guess is that plasmashell is not properly disposing of its textures. It takes a while for them to fill up VRAM, but then they start spilling into system RAM. I could test this hypothesis if I knew how to view how much VRAM is used/free. -- You are receiving this mail because: You are watching all bug changes.
