It has been over a year since version 5.12 was released. Fortunately, 5.13 is almost ready. Just as we have done in the past, we have prepared a release candidate for all of you to try before making the actual release. The goal is to ensure RawTherapee runs smoothly on all supported systems.
Please help us out by downloading the release candidate for your system and giving it a test run. Let us know what operating system and CPU you have and whether RawTherapee works fine. If you encounter an issue, you can report it here or at the official issue tracker on GitHub. See the instructions on how to file a good bug report here.
This release will be the first one to feature official ARM builds for Windows and Linux (macOS builds are already ARM-compatible). If you have an ARM computer running Windows or Linux, we would love to hear if the ARM builds work well for you.
I was able to run the Appimage on Ubuntu 24.04.4 (16Gb ram) several times over the morning (albeit with some issues) but now it simply crashes on startup. This may be something to do with my system because a self-compiled version behaved similarly. 5.12 runs without any problems.
The issues encountered with the AppImage when I could get it to run were as follows:
Slow to react on startup (system message asking me if I want to wait or force quit)
the Straighten/fine rotation tool seemed to be broken. When I started drawing the horizontal line the tool icon turned into a hand icon and started panning the image. The image also zoomed randomly to 100% on several occasions while trying to draw the line.
Color Appearance & Lighting
The new R,G,B Brightness curves invariably produce artifacts and should be disabled perhaps until the next release?
I have managed to get the self-compiled version working again after doing a fresh compile. The 5.12 Appimage also continues to work OK as do other Appimages but I still have the same problem with RC 5.13.
As far as the other two issues are concerned:
The problem with the Straighten/fine rotation tool seems to depend on how you drag the icon once youāve clicked on the starting point. If you drag it off at an angle away from the horizontal and bring it down (or up) to the endpoint, it works OK. If however you drag it almost horizontally, thatās when the icon changes to the hand icon and the image will pan and zoom, seemingly randomly, to 100%
The brightness-curve artifacts depend on the image and the editing but here are two crops using a neutral profile and no editing apart from a slight increase in the mid-tone brightness of the green channel in the second image.
Hi Paul,
thanks for checking. Iāve since tried the Appimage on an identical hardware setup running Ubuntu 22.04 LTS with no problems for either 1 or 2. I then fired up my 24.04 LTS machine and loaded the Appimage. It works fine the first time but if I close and reopen it, it crashes on start up. Restarting the machine produces the same result i.e. works the first time and then crashes if I close and reopen the Appimage. Everything seems to point to a problem with my installation.
I just tested it on Windows 11 (compiled version), and everything seems to be working normally. But that doesnāt prove anything at all.
The tests I ran (not these specific ones) - back when my grandson was here with a prototype of Ubuntu 26.04 and a Ryzen processor - lead me to believe that in certain parts of the code (where??), some instructions are sensitive to the processor type (specifically its precision) and the libraries involved. The changes I made fixed the issue on his machine (which had been experiencing random crashes). Pull Request 7629

But perhaps Ciecam also needs to be modified, as I had proposed here PR 7700
But perhaps thatās not itā¦
Iām going to test it on Ubuntu 24.04 LTS.
I just test on Ubuntu24.04.4LTS Linux 6.17.0-35-generic: no problemsā¦
But that proves absolutely nothing. Your machine might not have any problems at allā¦ (Iām talking about the hardware).
Iām running RT RawTherapee_5.13-rc1_x86_64_release.AppImage on OpenSuse Tumbleweed. Itās working fine, but Iām struggling with synchronization of metadata in image / xmp sidecar. This example of 2 pictures is about rating/ rank:
==> starting point, 2 pictures, metadata for tif embedded, for Raw in xmp sidecar
Does anybody have problem adding tools to local adjustment spots? Iām using 5.13 RC1 with my Simplified Chinese translation and canāt add: GHS (which I noticed has changed to Equalization and pre tone-mapping, will update it), é²ęåŗ¦&å·ę(Vibrance & Cool/Warm), å±éØåå·®&å°ę³¢(Local Contrast & Wavelets). I switched to Japanese and canāt add one thing at all. Iām assuming there is something wrong on my side and will test the zip version, but itās certainly weird.
For me, there are no issues with either configuration (Windows 11 and Ubuntu 24.04),
But anything is possible. Whatās curious is this avalanche of malfunctions with version 5.13, given that nothing significant has changed compared to dev or others PR.
Thanks for testing Jacque, I figured itās something wrong with my PC (I have multiple versions of RawTherapee for different purposes, so maybe things went messy because of that). A few month ago I also encountered a problem which no other people can replicate. So Iām glad that it seems itās only me and there is no actual problem with RawTherapee itself.
Hello Jacques @jdc , thank you, the secam16 x86 Appimage seems to have fixed both the crash and the artifacts generated by the Brightness curves. I have opened and closed it a dozen times or so without any problems. I only tried the Brightness curve on the image I posted above and there doesnāt seem to be any problem (with reasonable Brightness increases in any case). Iāll try it on a few other images tonight.
Thatās a good point Paul, I hadnāt noticed that. Iāll see if I can edit it without reformatting the disk.
EDIT: that seems to be the problem - I simply unmounted the disk and started and closed the Appimage several times without it crashing. As soon as I mounted the disk and selected it in RawTherapee, it crashed as previously. Itās strange though that this seems to happen only with this particular Appimage.
Thanks for your help Paul. In reality itās not completely solved because while unmounting the disk fixes the problem, removing the space in the label doesnāt. I went through and corrected a few other instances of spaces in the file or folder names but there must still be some lurking in there somewhere. As I mentioned above this isnāt a problem with Jacquesā @jdc secam16 branch but finding out why is beyond me especially in this heat.
