[12:37] <Spass> more info about the left and top screen edge flickering (e.g. Whisker) - did some testing on Kubuntu 18.04 and Latte dock doesn't flicker, but Plank does, so maybe it is GTK related?
[12:58] <Unit193> Did you try turning off gtk animations?
[12:59] <Spass> Unit193, no, where I can disable them?
[13:07] <Unit193> gsettings set org.gnome.desktop.interface enable-animations false  ?
[13:08] <Unit193> Was pretty sure it was in the settings editor under Gtk
[13:12] <Spass> ok, will try that
[13:22] <brainwash> Spass: it happens in 18.10 too, right?
[13:23] <Spass> brainwash, on Xubuntu 18.10 too, yeah
[13:23] <brainwash> ok
[13:25] <Spass> didn't try other 18.10 flavours, but I assume it's the same
[13:26] <Spass> Unit193, animations disabled, Plank still flickers
[13:28] <brainwash> I would ask in the gtk channel on the gnome irc network, maybe they can help you identify the cause of this bug
[13:29] <Spass> not sure if it's really GTK-related, but I tried so many things so far... on couple distros
[13:29] <brainwash> you have to start somewhere
[13:30] <Spass> it began somewhere in the 17.04 era and it persist from then
[13:31] <brainwash> the gtk people surely know some tricks on how to debug something like this
[13:31] <Spass> so maybe that is a clue, maybe a specific GTK version, Xorg version / something else was introduced that time
[13:32] <Spass> brainwash, here's some more details - https://ubuntuforums.org/showthread.php?t=2397371
[13:32] <brainwash> 16.04.5 should have newer xorg and kernel, maybe worth giving that older version a try too
[13:32] <brainwash> see if this bug was introduced in that release also
[13:33] <Spass> sure, will try, I have that ISO so I'll burn on my USB now
[13:33] <brainwash> it does not happen when using a VM, right?
[13:34] <brainwash> VM in full screen mode
[13:34] <Spass> yes, all good when in VM
[13:34] <brainwash> ok
[14:16] <Spass> brainwash, just tested Xubuntu 16.04.1, interesting info that may suggest that it's indeed a GTK3-related issue
[14:16] <Spass> Plank flickers, but Whisker menu doesn't
[14:17] <Spass> I think that 16.04.5 has Whisker still as a GTK2 plugin
[14:18] <Spass> and Indicator Plugin on the panel (WiFi, Bluetooth and sound) flickers, and I think it's a GTK3 plugin
[14:19] <Spass> so to summarize, seems like there's something wrong with GTK3 apps / elements on top and left screen edge
[15:35] <brainwash> Spass: you tested with both .1 and .5?
[15:35] <Spass> only with .5
[15:35] <brainwash> so it was a typo
[15:36] <Spass> oh, sorry, yeah didn't notice that typo
[20:46] <Unit193> bluesabre: I slipped xfwm4 in as a bugfix release (because, well, it's a bugfix release..)
[21:37] <bluesabre> Unit193: that makes sense :)
