Window Masks

[Cardellino]

Hello, after today's update, the shifting of the window masks no longer works.
My system is:
ArchLinux x86_64
Kernel: 6.0.2-arch1-1
Deepin 20.7.1.

Many thanks in advance

I don't understand what does "Window Masks" means, could you be more specific so we can better understand what went wrong? Thanks!

What if you run deepin-wm --replace & from a terminal?

Hello Blumia,
with deepin-wm --replace & then everything is fine.
This is the error message from the console:

~]$

As soon as the console is closed, the same problem as before
Thanks for the support

Oh, you can also use nohup deepin-wm --replace as a workaround.

ps. I managed to reproduce this issue. If you haven't clean your package cache, you can also downgrade startdde to startdde-5.9.56-1 as a workaround: sudo pacman -U /var/cache/pacman/pkg/startdde-5.9.56-1-x86_64.pkg.tar.zst

With a downgrade everything works again.
Thank you for your support...

The package maintainer already released a fix (startdde 5.9.59-2) so you can safely upgrade the package once the mirror you use synced the packages :)

[BLumia]

Dive into the source code and seems it's a bug in startdde 5.9.59 (caused by this line). You can use any one of the following as a workaround:

1. Start deepin-wm manually via nohup deepin-wm --replace from the terminal. or
2. Open dconf-editor, locate to /com/deepin/dde/startdde/wm-cmd and change the value to /usr/bin/deepin-wm. or
3. Rollback to startdde-5.9.56-1 if you haven't clear package cache: sudo pacman -U /var/cache/pacman/pkg/startdde-5.9.56-1-x86_64.pkg.tar.zst

The bug has been reported to the Arch Linux package maintainer and this issue will hopefully get fixed in the next day with startdde-5.9.59-2 or so. Once the new package has been released then you'll be able to just upgrade the package and everything will work again! (if you did the 2nd workaround solution, don't forget to restore the change once the package get updated :) )
