Dear Maintainer,
after upgrading my KDE jessie system I noticed that plasma-desktop was pretty unresponsive (panels taking a long time to respond.)
Seems to be the same thing as https://bugs.kde.org/show_bug.cgi?id=273214.
Killing and restarting plasma-desktop helps only for a short while.
I did run the CPU monitors in Ksysguard (it might be related to those according to the KDE Bugzilla; I'll check if it still happens after I reboot.)
While plasma-desktop sucks CPU I see many of these with strace:
stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=2819, ...}) = 0
stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=2819, ...}) = 0
write(3, "\1\0\0\0\0\0\0\0", 8) = 8
write(3, "\1\0\0\0\0\0\0\0", 8) = 8
write(3, "\1\0\0\0\0\0\0\0", 8) = 8
write(3, "\1\0\0\0\0\0\0\0", 8) = 8
stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=2819, ...}) = 0
stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=2819, ...}) = 0
write(3, "\1\0\0\0\0\0\0\0", 8) = 8
write(3, "\1\0\0\0\0\0\0\0", 8) = 8
stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=2819, ...}) = 0
stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=2819, ...}) = 0
write(3, "\1\0\0\0\0\0\0\0", 8) = 8
write(3, "\1\0\0\0\0\0\0\0", 8) = 8
stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=2819, ...}) = 0
stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=2819, ...}) = 0
write(3, "\1\0\0\0\0\0\0\0", 8) = 8
write(3, "\1\0\0\0\0\0\0\0", 8) = 8
stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=2819, ...}) = 0
stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=2819, ...}) = 0
write(3, "\1\0\0\0\0\0\0\0", 8) = 8
write(3, "\1\0\0\0\0\0\0\0", 8) = 8
Downgrading to plasma-desktop=4:4.8.4-6 did not fix the issue.
