@stefan.chirila @Morgan_Hardwood I have updated all the AppImage packages in Release Automated Builds · Beep6581/RawTherapee · GitHub with the fix to the fonts issue.
Finally I went for a more complicated, but better, solution to this problem. The version of the fontconfig library that is used is determined at runtime, based on the versions of the bundled and system libraries. If the system library is newer than the bundled one it will be used, otherwise the bundled one takes precedence.
Thais seems to be working fine on all systems I tested, ranging from Ubuntu 14.04 to Debian-testing.
Could you please double-check it and, if ok, update the official link in the RT Downloads page?
Thanks!
@stefan.chirila RawTherapee does not use SVG icons anywhere as far as I know.
Nice cat.

/tmp/.mount_yLbNRR/usr/bin/rawtherapee: symbol lookup error: /usr/lib/libEGL.so.1: undefined symbol: gbm_bo_create_with_modifiers
I’m building a new RawTherapee-dev-5.4-* package that should fix the undefined symbol. It should be ready in about 30 minutes…
@Carmelo_DrRaw a987c280aea2bbbf18c0917e550cc4c4 RawTherapee-dev-5.4-266-ga84ce624.AppImage ran without crashing, but it was very slow in some ways. Panning the main preview or adjusting a curve felt close to normal, but right-clicking on a different thumb in the File Browser takes 2 seconds to show the context menu, and switching from the Editor tab to the File Browser tab, and vice-versa, takes 10 seconds and makes my whole system jerky. No warnings nor errors appear in the console while this happens. Preferences also takes about 10 seconds to appear and over a second to close.

@Morgan_Hardwood well I’m glad I’m not crazy and others find things sluggish too. Same thing with the Gimp 10 appimage. Seems like the Gimp image works fine.
@Carmelo_DrRaw Okay so I did what you said to do. It’s running, but no difference in behaviour. Some things are a tad choppy, and it feels like its taking a fraction of a second to think about what it needs to do before implementing it …like for example changing the Brightness slider in RGB mode. Would the Warnings on the right in command line regarding Gtk have anything to do with it.
My installed debian 5.0 runs way smooth, but it’s GTK2 compiled.
Okay so everything so far aside; I did a distro-update on my debian laptop and am getting the following error when trying to run the RawTherapee appimage. needless to say it doesn’t even start up 
Gimp one works however.

stefan@stefanTHINKPAD:~/APPS/RAWTHERAPEE-4.5$ uname -a
Linux stefanTHINKPAD 4.9.0-6-amd64 #1 SMP Debian 4.9.82-1+deb9u3 (2018-03-02) x86_64 GNU/Linux
Update:
Funny enough, the appimage that is on the rawtherapee downloads page (the one that needed changes and wouldn’t run on my desktop) now works on the laptop.
I made few changes in the way the fontconfig libraries are detected and handled, such that the AppImage should work fine on both old and new systems.
RawTherapee-dev-5.4-266-ga84ce624.AppImage should now work OK on both your laptop and desktop. I will update the other packages once I have confirmation for this one.
I am now trying to figure out the reason for the sluggish performance of the UI that you and @Morgan_Hardwood reported, and that I can also reproduce. It seems to be related to SVG icons being loaded instead of PNG ones, but I am still investigating…

@Carmelo_DrRaw man I just wanna say I really appreciate your tons of effort and the real swift replies. It is a pleasure to be in this forum and see the real time developments in the updating of one of my most favourite pieces of software in the whole wide world 
Update:
BTW; if you manage to figure it out, what is the error message caused by, is it once again regarding fonts?

@Carmelo_DrRaw Just tried the RawTherapee-dev-5.4-266-ga84ce624.AppImage image on tower and laptop. It runs but considerably slower than your previous file.
Good! It means that the font issue is probably fixed. I’m still investigating the performance issue, I have some ideas but no conclusions yet, as I need to rebuild my custom Docker container.
@stefan.chirila @Morgan_Hardwood I have prepared a new version of the AppImage that, at least on my Ubuntu 16.04 system, runs practically as fast as the native 5.4 version installed from PPA. The link is here: https://github.com/Beep6581/RawTherapee/releases/download/nightly/RawTherapee-dev-5.4-266-ga84ce624.AppImage
Could you please check if you see a similar speed improvement? If yes, I will update the rest of the AppImage packages in the nightly release…
Thanks!
@Carmelo_DrRaw speed is good. will check it on laptop right away. but not sure which language this is in …looks like portuguese?
On the laptop however, it shows propper English, but the font it picks is some random medieval one I have in my fonts folder 
Thanks for checking! Could you send me the terminal output in both cases? Also, are you able to fix the font issue in the preferences, or there is no way to change the medieval one?
@Carmelo_DrRaw
Terminal output for laptop: (I ran the image and then copied and pasted whatever the terminal had in it until RawTherapee started up)

I must have done something to my fonts folder I wish I were more knowledgeable.
@Carmelo_DrRaw updated reply 
@Morgan_Hardwood @stefan.chirila
Given that the most of the issues discussed here seem to be solved in the latest RawTherapee-dev-5.4-* AppImage (and in particular the slow UI), are you OK if I update the rest of the AppImages as well?
@Carmelo_DrRaw I tested:
https://github.com/Beep6581/RawTherapee/releases/download/nightly/RawTherapee-dev-5.4-271-gfde0dccd.AppImage
Clicking on a main tab now takes 1 second. That is still slower than a native build, but a great improvement 
What was the cause of the slowness and how did you fix it?
The console still shows:
Gtk-Message: 13:26:32.026: Failed to load module "canberra-gtk-module"
which probably means that audio feedback won’t work.
