Dex is not filling the Scrcpy window

[Obsidiannite21]

• I have read the FAQ.
• I have searched in existing issues.

Environment

• OS: [e.g. Debian, Windows, macOS...] macOS
• scrcpy version: [e.g. 1.12.1] 2.1
• installation method: [e.g. manual build, apt, snap, brew, Windows release...] brew
• device model: S23 Ultra
• Android version: [e.g. 10] 13

Describe the bug
After upgrading to 2.1, when I launch scrcpy --display 2, it gives the following WARN: Display doesn't have FLAG_SUPPORTS_PROTECTED_BUFFERS flag, mirroring can be restricted
INFO: Renderer: metal

The window is able to be resized but the Dex desktop is much smaller the the actual window. It's easier to understand if you check out the attached screenshot. It is likely related to issue: #4120 but it looks like that was resolved. Am I missing something?

On errors, please provide the output of the console (and adb logcat if relevant).

Please paste terminal output in a code block.

After upgrading to 2.1

Did you have the same problem with earlier versions?

If you record (scrcpy --record=file.mp4), are there any black padding in the recorded file like in the screenshot?

As a workaround, does cropping work correctly?

[Obsidiannite21]

@rom1v No, but to be fair this is the first upgrade I've done since I installed it.

Yes the recorded video contains the black padding like the screenshot.

Yes scrcpy --display 2 --crop=1080:1920:0:0 -e fixes the issue, thank you for the work around!! I was looking for one but didn't see crop.

I also have the "same-ish" issue it seems, but manifested when using the simulated display mode.

[nikp123]

The issue seems that scrcpy is grabbing the wrong texture size. It takes the resolution of the primary display (aka the phones) rather than of the the display that you're targeting.

Could you please test on dev branch? #4120 has been fixed since scrcpy v2.1 (808bd14)

Do I need to build the scrcpy-server part because I am having NDK difficulties.

Do I need to build the scrcpy-server part

Yes, the change impacts scrcpy-server. You don't need the Android NDK to build scrcpy (just the Android SDK).

Anyway, here is a release of the current dev branch:

• scrcpy-win64-v2.1-6-g01d785d9a.zip SHA-256: 9b07defe03291d39b89daff9f26667abac2ca342393b63e076de3f6b54a418f4

Thanks, will test when I get home on my Windows PC (in about 3-4 hours), sorry for the delay

[nikp123]

@rom1v sorry for the additional delay, yes the issue has been fixed.

[rom1v]

@Obsidiannite21 Is the issue also fixed for you?

[Obsidiannite21]

@rom1v How would I install the dev branch using Brew on MacOS?

[rom1v]

Take scrcpy-server from the zip (I guess the client changes are not important), and execute:

export SCRCPY_SERVER_PATH=/the/path/to/the/downloaded/scrcpy-server
scrcpy

(adapt the path)

I'm using Arch Linux and got the same display problem
after got the scrcpy-server extract from the above zip file
and run with it SCRCPY_SERVER_PATH=~/Downloads/scrcpy-win64-v2.1-6-g01d785d9a/scrcpy-server scrcpy --display=2
finally it display correct. thanks so much.

[rom1v]

👍 The fix has been released in scrcpy v2.1.1.

how are you activating Samsung Dex (or Android Desktop)? mine just stays in cellphone mode.

[Obsidiannite21]

I connect my S23 to a hub that has a monitor attached. That allows me to mirror OR run dex, depending on how you run Scrcpy. Some use fake HDMI dongles. I haven't found a "software" solution to run Dex using Scrcpy but if in your search find one, please let me know.
