Describe the bug

When one of my colleague sent MOV video from her iphone to #general chat, many another colleagues went with Electron RC into gray screen and nothing worked ...

It's not the first time when this issue happens. Blind clicking to the left bar work as workaround - you will escape the problematic chat and issue with rendering disappears. When you click back to problematic chat, you go back to gray screen or app crash (depends on GPU acceleration, etc.)

How to Reproduce

1. Send MOV from iPhone as described above.
2. Open the chat at MacOS client
3. See gray screen

Describe your Expected behavior

Working RC even with the video in chat

@dusatvoj, could you provide us with the video file that is breaking the app? I tested with some videos from my iPhone 13 and my Galaxy S23 Ultra and had no crashes. But we already had some reports from other users, so the file would help us understand what's going on. But I can tell you that is totally related to hardware acceleration on macOS, because if you disable it on the desktop app, the crashes stops.

@jeanfbrito , this video breaks my colleague's RC electron app @ macbook

IMG_7134.mov.zip

[samir0607]

@dusatvoj I have sent this particular video on #sandbox and it's running perfectly fine on the RC electron app in macos

[dusatvoj]

Weird, don't know what can be wrong or how can I help to better reproduce it. Maybe there's some fix in v7.x? 🤔 I'm running server v6.13.x. (LTS)

[jeanfbrito]

It just happens when running the Apple Store version.

[jeanfbrito]

@dusatvoj please test the version 4.1.4 that is on Mac Apple Store, it should not crash the screen anymore.

[dusatvoj]

@jeanfbrito , it happened again to the same colleague, now with 4.1.4 🙈

At least one output file must be specified

... with this video 😕 (not sure why he has that old client)

[jeanfbrito]

Let me revisit this now. But it was a bug with the hardware acceleration and the only solution was to disable it. Its more an issue from the Apple side.

[dusatvoj]

My colleague tested that with 4.7.1 now and it's still broken. Of course it can be caused by 🍎
