When i try to preview my scenes a "new" preview window appears and is "off center" and it plays in real time with out lagging. Sometimes that new "window" is not even visible (depens on how much you have zoomed into the scene) adn the original workspace area is just static. I hope my screenshots makes the matter more clear, since it is hard to explain in words. Also, sliding the current time indicatior manually works - Then the "real" preview window is showing what it should.

Both screenshots is taken during preview. When preview is stopped everything looks normal

I put this simple expression on a master property that cycles through some items. It shows 1, 2, 3, 1, 2, 3, etc. on the control, but it only shows the item #1.

timeToFrames(time/50) % 3 + 1;

This wasn't working on another master property, but it started to at some point on it's own. I've tried purging, recreating the property. About the only thing I haven't tried so far but sometimes works is recreating it all in a new comp.

When playing preview by pressing the spacebar or using the preview panel it does not stop by pressing the spacebar again and the interface is unresponsive. (CC 20 - v17.0)

When a fresh shortcut text file is made in CC2020, then going to in and out points doesn't work when pressing i and o. Tested by using a previous custom shortcut text file which works fine. Then removed to generate a new fresh one and the buttons don't work

The ram preview plays but is displayed about 200 pixels right and 200 pixels down in the comp window, you can see the current comp frame behind it. its cut off by the edge of the comp window

In AE CC 2020, the Roughen Edges effect still shows the original edges of shapes and vectors. It also produces oddly colored edges.

This wasn't the case before this version. It used to produce nice rough edges.

RAM Preview speed has improved but the entire program becomes unresponsive to clicks, spacebar, Num0, ESC, etc. Playback continues on loop and the only way I've found to regain control is to minimize/maximize AE.

AE 2020 fixed ram preview for me... YAY! However, Numberpad "." no longer previews just the audio. If I hit the "." key, the play-head moves across the timeline, but there's no audio... and I don't see anything in the audio levels display either. If, however, if I enable video preview in the Numberpad "." preview, I get audio... AND video—which obviously defeats the purpose of an audio-only preview.

Updated to Ae CC 2020 and going to the beginning or end of a layer isn't possible because the shortcuts (keys I or O) are not working.

When I try and load up a section of a composition to preview it doesn't play back smoothly even after it is cached.

Found a very easy way to replicate buggy behavior with CC Vignette.
1.Put any image or media in the timeline
2.Create an adjustment layer on top of it and add CC Vignette.
3. set a couple position keys on the adjustment layer and animate it.
4. You should see lots of strange behavior on the layers beneath the adjustment layer.

I ran into this issue lots when working with full-screen comps that had to shift over to split-screen.

AE always crashes if you do the following procedure.

1. Launch AE
2. Create New Comp
3. Creat New Solid
4. Duplicate the Comp
5. Open the duplicated composition
6. Lock the cloned composition viewer
7. Open the first composition you created in the timeline tab
8. Center the anchor point with the shortcut
9. crash.....

以下の手順を行うと必ずAEがクラッシュします。
1. AE を立ち上げる
2. 新規コンポジションを作成
3. 新規平面を作成
4. コンポジションを複製
5. 複製したコンポジションを開く
6. 複製したコンポジションのビューアをロックする
7. 最初に作ったコンポジションをタイムラインのタブで開く
8. ショートカットでアンカーポイントを中央に持ってくる
9. クラッシュする

Typing localeCompare() into any expression immediately crashes After Effects!

This also occurs with the majority of autocomplete options for "locale".

I no longer get a pop up warning me that AE is needed to run the .mogrt in Premiere with the TSV data...
The data is no longer read in Premiere, which it was before the last "upgrade"
Is there any troubleshooting tipd for TSV based expressions in mogrts?

I always thought a ram preview meant the preview would play back from ram in real time. this is often not the case. Most the time, especially comps with audio, don't play back in real time even if they are committed to ram or disk cache (Which means you either get the warped record slow down, or if that's muted in settings, nothing at all)...why is this, on every machine I've worked on...

Steps to Reproduce:

• Apply an expression to a property
• With that property selected, go to the Graph Editor
• Right click on the graph and enable "Show Expression Editor"
• Click on the expression editor Result: AE freezes

Throwing Errors is very helpful when debugging expressions (see https://twitter.com/mamoworld/status/1101168951185289217 )
However, currently on Windows the thrown error message is not shown in the status bar. On Mac this already works nicely.

The reason seems to be some subtle differences of how exactly the banner messages are shown on Mac/Win (see https://twitter.com/1ResCreation/status/1117325915007016962)

Please make Win behave the same as Mac for this and show the message directly in the status bar.
