Description hiro yamamoto 2021-02-09 15:19:18 UTC

Description:
We will give animation effects to some objects and play them back in order. However, depending on the type of effect, the playback will be disrupted. The problem is as follows
1. The playback cannot be backed up.
2. Several plays are executed at once.
3. Playback seems to be going on in the background after the problem occurs, the key (RightArrow) is responding, and the slideshow ends when it reaches the last playback. However, depending on the behavior before and after, nothing may be playing.
The above is not a guarantee that these things will happen. It depends on the case. The source of the problem has been confirmed, but the regularity of the result of the problem has not yet been found.

Steps to Reproduce:
1. give the animation effect of multiple objects. 2.
2. giving one of them an appearance animation effect, such as Zoom.
3. the divergence point is to give Moderate's Zoom etc. except Basic_Effect.
4. Play the object given it.
5. after playing the object that has that particular effect, the problem happens.
Other confirmation tasks
1. happened in ver7.1 and above.
2. it happened when I played a file that was created with ver6.1.
3. when I opened a file created in ver7.1 with ver6.1, it didn't work as if the bug had infected it.

Actual Results:
1. The playback cannot be backed up.
2. Several plays are executed at once.
3. Playback seems to be going on in the background after the problem occurs, the key (RightArrow) is responding, and the slideshow ends when it reaches the last playback. However, depending on the behavior before and after, nothing may be playing.
The above is not a guarantee that these things will happen. It depends on the case. The source of the problem has been confirmed, but the regularity of the result of the problem has not yet been found.

Expected Results:
If you select an animation effect type other than basic, it should still play correctly. The order should not be skipped several times as you move forward.
A situation where it is always possible to go forward or backward is preferable.

Reproducible: Always

User Profile Reset: Yes

OpenGL enabled: Yes

Additional Info:
In addition to this, the apparent disruption or deformation of shapes occurs when the file is opened. Or, the shapes are deformed when you perform operations such as grouping, or save and reopen the file. When I run a slide show, there is no problem.
It happens in the editing screen. We are currently challenging the status and reproducibility of the problem.

You can't confirm your own bugs. Moving it back to UNCONFIRMED until someone
else confirms it.

Comment 4 hiro yamamoto 2021-03-31 04:23:29 UTC

Thanks for the correction.
Currently, I can't download the latest version from my residence.
I can't check with the latest version.
I hope someone else can confirm the same situation.

Additional testing of the playback procedure, please.
I would like you to add the following test to the procedure I pointed out at the beginning of the problem.
(plus alpha)
　　Please make sure that the animation effect "Zoom" is given to two objects and that they play back in succession.

I'll upload the test file, and I'd like someone to check the problem.




Steps to Reproduce:
1. give the animation effect of multiple objects. 2.
2. giving one of them an appearance animation effect, such as Zoom.
3. the divergence point is to give Moderate's Zoom etc. except Basic_Effect.
4. Play the object given it.

Gives an animation effect to four or more objects. Give two of them a "Zoom" effect. Then play them.
If you play it backwards, it will behave strangely.

This was fixed last year.
