Created attachment 113017 [details] Desktop with Conky and Kinfo-screen Hi, Just tried the slidewhow again, now with KDE Plasma 5.12.5, Frameworks 5.46 and Qt5.11. Eventhough, as was said, the memoryleak would have been taken care off, I'm sorry to say but it's still there. When my laptop starts it consumes around 800MB of memory. With a slideshow changing time of 5 sec. it was not long when I had used 2GB already. No other programs started, except which was running all the time: Conky to show me the increase in memory.
Please confirm that Qt version number in kinfocenter. If you still have an issue I want to see a trace in massif.
Created attachment 113027 [details] System monitor I added a screenshot of the Kinfo center in my first post, you can see it there. What does this mean: If you still have an issue I want to see a trace in massif. I add another screenshot, now from system-monitor, on which you can see that the blue memory line is not changing much anymore (I have 4GB) but the red Swap line is constantly getting higher.
run kquitapp5 plasmashell valgrind --tool=massif plasmashell (it will be a bit slow, but try to keep it running and reproduce the leak) then send me a log
1) I installed valgrind and massif-visualizer 2) I then typed both commands in a terminal 3) Changed wallpaper to slideshow, refresh time 1 sec to speed things up 4) In the Conky on my screen I see NO increase in memory use 5) With ctrl-C I stopped the valgrind command 6) I then typed plasmashell to get my desktop, slideshow is still active 7) NO memory inscrease 8) Stopped the plasmashell command 9) Rebooted 10) Memory is filling rapidly, slideshow is still active, refreshtime is 1 sec. Found the massive fie, attach it.

Created attachment 113031 [details] 2nd test with valgrind --tool=massif plasmashell I've done the test again, now a bit longer but when plasmashell is started from a terminal, with or without valgrind, there is no memory increase at all. When I reboot and plasmashell is started the normal way, memory fills up.
Created attachment 113160 [details] Start of 5 minute test with interval of 5 sec. I did a 5 minute test with the slideshow active. In the two pictures you can see the memory use at the bottom left of the pictures. As you can see the second one is almost double ofthe first one. Nothing was done with the machine, no programs were started or whatever, I just sat in front of the screen for 5 minutes watching the memory use go up with every change of the pictures.
Created attachment 113161 [details] End of 5 minutes test This is the 2nd picture, taken 5 minutes after the first one. I also show Kinfocenter to show I do use Qt5.11 Memory use is almost double of that in the first picture.
I did a complete re-install of the OS and now the error with the wallpaper slideshow is gone. No idea what is different now. This bug can be closed now. Thanks.
:/ Ok, let me know if it happens again.
