Transition button issue with slide show

[cowface64]

My OBS Windows installation for a church has a Transition button issue with Image Slide Show. Using the Studio Mode, (1) I click on the scene containing a single Image Slide Show source, (2) and then push the Transition button to move it from Preview to Program. This works just like it should: the source transfers to Program.

I have the right and left cursors tied to this Image Slide Show source in Hotkeys, so that I can advance the slides using the cursors. Once the source is in Program, I use the right cursor button to advance the slides. The 1st and 2nd slide advances as normal, but when I try to advance the 3rd slide, the Transition button goes gray. It stays gray after that point, no matter what source type I try to run (Video Capture Device, Media Source, etc.) The only recovery mechanism seems to be taking OBS out of Studio mode and then putting back in.

To be more specific, the issue is not really tied to the 3rd JPG slide in the stack, just the 3rd time that the slides are advanced. So I can start with the 5th slide in the stack upon entry into the Image Slide Show source, and then Transition grays out on when I reach the 8th slide.

This issue seems very repeatable with a variety of Image Slide Show sources running my JPG files. I do notice that it can be avoided by doing steps (1) and (2) above and then choosing another source for Preview immediately before advancing any slides. With a different source in Preview, the issue does not happen while advancing slides.

I have a screenshot video I can submit if required (about 40 Mbit)

I too experience this issue with the recent update. I did discover that clicking on the T-bar would restore the transition feature. You don't actually have to move it. Just click on it.

This is definitely a bug and a pretty annoying one as it makes OBS difficult to use for our non-technical users.

I was hoping to do a more detailed reproducer to capture some logs so a bug report could be created but oddly enough I was not able to reproduce it when I had the time. I tried for nearly an hour and gave up. As I was packing up to leave I noticed that I somehow had 2 fade quick transitions so removed the duplicate. After I removed it I was once again able to reproduce the issue but I had ran out of time. Maybe I can get some time in the next couple of weeks to do some more testing.

I have the same issue. The transition button becomes gray after moving through 3-5 slides. The workaround I found until fixed, I use the slider to transition the preview to production. Then the transition button becomes active again.
