Andrea, thanks again for testing. GG has worked all day to provide fixes in order to use caching to get the speed up for transitions and reverse playing. There is another GIT checkin if you want to test again and hopefully no more freezes. I almost always run using X11 as my Video driver but now I am testing with OpenGL too. So far no problems. About "Note: I didn't use move/swap tracks up or down! I don't understand why these entries are present." I turned on Perpetual Session early this morning and have been running all day with it. GG deduced that the reason you see "move tracks up/down" is because you are accidentally using the shortcut of Shift-up arrow and Shift-down arrow. But there is no shortcut for "swap tracks up/down" so we do not have an explanation for that. gg/Phyllis On Sun, Sep 13, 2020 at 2:20 AM Andrea paz via Cin < [email protected]> wrote:

I was testing the new git release to test the fps drop with transitions and the crash with fast reverse.

I also have freeze (not crash) if I use fast reverse. It doesn't happen every time; it happens more often if transitions are present and if I use "Perpetual session". No problem in X11, only with X11-OpenGL.

For me the problem of transitions is solved: there is only a small drop in fps, but it is instantaneous and immediately restored. The drop is more accentuated in Reverse, but immediately restored. Even with "play every frame" I have a more pronounced drop but this is also immediately restored.

But I noticed that simply putting a transition in timeline leads to some messages in terminal (Messages that are repeated for each transition applied). This happens only if "Perpetual session" is active:
