Enough for me not to consider attempting it.

I agree.

Thanks for your input.

You could try backporting it but you would probably have to also backport several other packages and then keep them updated manually afterwards. Probably not worth the bother.

Hmm ...
There must be a solid reason for experimental.  8^D

I remembered looking up this once.
It seems that dpkg -i package_file.deb does not take care of dependencies prooperly or at all.

Which apt install ./package_file.deb does:

groucho@devuan:~/Downloads$ sudo apt install ./libgtk-3-0_3.24.29-1_amd64.deb
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Note, selecting 'libgtk-3-0' instead of './libgtk-3-0_3.24.29-1_amd64.deb'
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

My guess is that I'd have to fetch all these unmet dependencies from experimental also.
But I'd rather not dive into dependency hell and be sure.

I think I'll live with the occasional crash and wait.
In any case I'll eventually be ditching Xfce4.
I don't like where it is going, so I may try LXDE, à la Knoppix Live or a #! solution.

Thanks for your input.

Thanks for the heads up.   8^)

So ...
Download the .deb and install with dpkg -i libgtk-3-0_3.24.29-1_amd64.deb?
Or is there a better, more fool-proof way?

Thanks in advance,

A.

Apparently (?) the problem has been fixed/worked around.

https://gitlab.gnome.org/GNOME/gtk/-/issues/3715

From what I think I understand, a patch has been written up so that the affected applications don't crash.
ie: the root of the problem (in xfce4?) will remain where it is till the next time someone reports something else.

The Devuan Beowulf repository has libgtk-3-0 3.24.5-1 and the Chimaera repository has  3.24.24-3.
The patch is in 3.24.29.

How can I go about checking to see if 3.24.29 fixes the problem?

Thanks in advance,

A.

I looked at Gnome under Debian just once years ago in my first attempt at Linux.
Not really what I was wanting to see.

A couple of years later I used Cinammon and then Mate in a few other distributions.
I did not like them too much, really didn't see any need for so much bling and flash.
You have MS for that type of thing.

#! Linux with it's customised Openbox WM was great but that distrubution went south in 2015.
Then systemd crept into everything around me but then found Devuan which came with with Xfce.

As time goes by and I use it more (no more office IT work+MS stuff to deal with), I find Xfce more and more annoying.
The fact that at v4.12 Xfce has not been able to get icon behaviour working properly is really annoying and if 4.16 ends up being what it says it will be ...

But I do mind.
Both in principle and in practice.

Things are what they are in IT because the concept of lean and mean has long been abandoned.
Intelligent/clean coding seems to have become a thing of the past.

If those chaps who write those absolutely incredibly efficient viruses in 8 or 10 lines of code used their skills to write a Linux desktop, Linux would be the king of the desktop PCs today.

Yes, one highly adaptable and configurable desktop, instead of the absurd number of bloated DE we have today.
There's far too much crap (and time/effort spent) in the name of a mis-interpreted freedom within an ecosystem where everyone and his dog wants to be a prima donna.

Right.
I will now quietly step off my box and go have my second morning espresso.
Maybe then I'll feel better.  8^7

Thanks for your input.

The issue is evidently xfce4 inter-component related.
And from what I have seen with how the 4.16 version is coming along, things won't get better.

It's a pity but that's how it is rolling these days.

So I won't insist with Thunar unless PCManFM ends up not being up to par and have to try something else.
I already have a parallel Beowulf installation that I am attempting to build up as what at one time #! Linux was, I really liked it.

Thanks a lot for your input.

# apt install compton

then in a terminal

compton -b

then do drag and drop in thunar and see what messages if any print in the terminal.

control -c to cancel compton.

Yes.
It's all xfwm4: thunar, compositing, etc.

Unfortunately, removing thunar is a messy affaire.
It is so ingrained into Xfce and the desktop that without it, the icons on my desktop would not open and the system complained about org.xfce.filemanager not being found.
The workarounds I found on the web did not work and I had to install it again, bringing along thunar-volman.

It's a real pain in the ass and yet another reason to consider dumping Xfce.

Thanks for your input.

A.

Does not make any difference, it is not a mouse problem.

Given my observations, I have concluded that this is a problem with thunar and how it interacts with compositing.
Maybe it is related to how Xfce intruments compositing?

The maintainers at gitlab.xfce.org first made a reference to my using " ... outdated versions of the various involved components (Thunar, GTK, X and xfwm4) ..."
They have told me me that no one else has reported it and had not been able to reproduce it.

On their suggestion, I also tried to get a backtrace but the gdb utility did not produce a stack on thread apply all bt full or bt.
Alternatively, running it as root completely froze my desktop and did not produce a stack either.

So there's evidently something wrong there.

So I will just get rid of thunar and stay with PCManFM.
It seems to work quite well and most importantly, does not crash under the same conditions thunar does.

Best,

A.
