My issues with lxpanel 0.10.2

[pitsi]

Sorry for the very generic title, but this is all I can think of right now.

I am a debian user who was affected by debian's gtk3-upgrade of all lxde apps. Out of all the apps, lxpanel became the most broken one, sadly. There are 2 open bug reports, one of which is labeled as grave (the highest severity in debian's bug tracking system) and another one which contains a number of patches for lxpanel 0.10.1.
The most annoying issue for me on that version was lxpanel moving outside the screen boundaries. I also had the tooltips that appear on the top of the screen (panel is at the bottom) and some broken app icons that showed up as white.
For that reason, I asked someone to patch and package lxpanel for me, using all the forementioned patches. He did, but they only solved the "geometry issue" (i.e. the panel moving outside the screen borders.

Then I found your github repo, noticed the new 0.10.2 version that fixes several stuff so I asked him to build that one too. Your version fixes the tooltip issue, but the others remain. More specifically:

Some app icons are drawn as white/blank, e.g. thunderbird here is one of them which has issues. If I kill lxpanel and relaunch it, it sometimes shows up like it should. The tooltip at the first image is there to show that tooltips are working properly.

Other than that, the icons that are drawn properly, are cropped both at the top and bottom as you can see here. No patch fixed this.

And last but not least, the panel itself follows the bright "version" of the gtk3 theme. I use numix as my gtk theme since ages and the panel, at its gtk2 era, had that dark color its menu has. Just to be sure it is not a gtk3 issue, I tried xfce4-panel (v4.18.4, stock configuration, just moved it at the bottom), which is definitely built against gtk3, and it is dark indeed.

My panel layout is very simple: menu + seperator + task bar + tray + digital clock + application launch bar (the single icon on the far right). And all of these issues are related to the gtk3 transition. It had no issues on gtk2.

$ lxpanel --version
lxpanel 0.10.2.r1

One more minor annoyance. If I leave the mouse over one of the taskbar's... tasks, the tooltip constantly blinks on and off.

I just had the second segfault with lxpanel 0.10.2. I had the first one a few days ago, but I was too busy to look in dmesg etc

And another one

I had a couple of xorg freezes the past days and I thought brave was to blame, because I had to switch to a tty and kill it. As it seems, lxpanel was to blame, because it could not switch between brave's windows and it segfaulted after a minute or so, producing the same output as above in dmesg.

I wanted to write today "it has now been 2 months that I disabled the tooltips and lxpanel has been rock stable".
But a minute ago I did a... ninja move by right clicking a window and instantly pressing close. The window closed, but the lxpanel's popup with close/minimize/resore remained there and I had to kill and relaunch lxpanel to make it go away.
