Thank you for your bug report, is there any chance you could get a valgrind log?

[Pavol Klačanský (pavolzetor-deactivatedaccount)]

here is log from valgrind (I have done it using this page https://wiki.ubuntu.com/Valgrind)

Memory leak is not there, at least not big for sure, I do not know if it was fixed in recent updates, but on the other side, I have got pretty nasty crash (I have attempted display a bit bigger window than usual)

Status changed to 'Confirmed' because the bug affects multiple users.

Hello.

I have the same problem with xubuntu 12.04 and intel graphics adapter.
On other computer, with NVidia, this bug does't affect me.

[Daniel van Vugt (vanvugt)]

Thanks Pavol. Unfortunately you seem to have run valgrind on the "unity" python script. Actually unity runs in the "compiz" process and I don't have any simple instructions written yet for how to vallgrind (or 'massif') the compiz/unity process.

If you are comfortable with valgrind then please consider using "valgrind --tool=massif" to gather memory usage info. Again, sorry we don't have any explicit instructions written for it yet.

[Pavol Klačanský (pavolzetor-deactivatedaccount)]

I am not valgrind guy, can you please post whole command? thanks

I switched to xorg-edgers ppa. Now its a little bit better. But after some days the effect comes back.

Using:
KDE
xorg-drivers-nouveau

unity-panel-service is not leaking memory on 15.04+. The memory footprint tends to grow slowly but that does not mean there is actually a memory leak, it's just the way the kernel manage the memory. Please reopen the bug if you think the leak is still there.
