Remote window shows blank, no files listed or odd white space above remote file list, but remote files re-appear when app is re-sized

[Walter Cain]

Symptoms:
Log onto remote site : occasionally remote folders and file listings do not show - (remote panel completely blank). However, if the app window is re-sized, folders & file list suddenly shows correctly.
Seemingly random, often initial login is ok - folders & files all listed.
But click on a remote folder and the remote pane shows blank or is 'half filled' with listing.

Causes/triggers:
Can't see a pattern / can't identify any particular folder attributes that trigger it.

Workaround:
But always re-sizing of the Filezilla app will magically fix it (for that view only), folders & files will appear as normal. But go into another folder and the problem is back.

Very frustrating - v. difficult to work with this issue.

Tested across two machines, two different users: exactly the same problem - both users have same OS and Filezilla Versions.

What's your desktop environment? Which theme engine are you using for GTK+2 based programs?

I hope I've understood you correctly:

(Theme for Ubuntu 16.04: 'Radiance')

Are you using Unity, Gnome, KDE, XFCE, LXDE, Mate, Cinnamon or any other desktop environment?

[Walter Cain]

Standard UBUNTU

'echo $XDG_CURRENT_DESKTOP'

returns:

'Unity'

[Tim Kosse]

So far I've been unable to reproduce it on a local Ubuntu 16.04 installation with Unity.

What kind of graphics card do you have and which driver are you using?

[Walter Cain]

All other apps are ok - this is happening across 2 different machines here (both Ubuntu 16.04, both Unity).

One is: Graphics: Gallium 0.4 on AMD SUMO (DRM 2.43.0, LLVM 3.8.0)

The other is: Intel® Ivybridge Mobile

You are neither using the official FileZilla binaries nor using the version packaged by Ubuntu.

Did you compile FileZilla yourself or did you obtain it from a third-party repository?

The version of wxWidgets your FileZilla links again, does it in turn link against GTK+2 or GTK+3?
