[BUG] Black background in application menu on second monitor

[Majo111]

The background of app menu is often black on second monitor. There is a shot:

System:

• OS: Manjaro
• Version of V-Shell extension: 48
• Source of installation: [Extension manager]

Your second monitor is the primary one as I can see, right? Does it happen immediately after login? The background is OK in the overview and disappears when you open the app grid? Re-open the overview doesn't help? Extensions? Themes? Something in the log?

[Majo111]

Yes, you are right. It happens randomly. Sometimes there is all OK and sometimes not. In most cases is background in overview OK. Problem is only app grid. Reopen overview has no effect on app grid background. My extensions are Burn my windows, Coverflow alt-tab, Disable unredirect fullscreen windows, Hide activities button, Hide top bar, Transparent top bar, Vitals, V-shell, Custom accent colors, Dash to dock, Gnome 4x UI improvements, Legacy (GTK3) Theme scheme Auto Switcher, User themes and Pamac updates indicator. My theme is Colloid.

Have you tried my patched Dash to Dock for V-Shell? You can install it along with the original one, it has a different uuid. So after the installation disable Dash to Dock and enable Dash to Dock for V-Shell

[Majo111]

I have installed your Dash to dock, but problem persist.

[G-dH]

Can you add export SHELL_DEBUG=backtrace-warnings to your ~/.profile or ~/.bash_profile so we can see source of the warnings when the background disappears? Requires reboot.

Have you tried my patched Dash to Dock for V-Shell?

Sorry for off topic, but I'm curious what exactly has been patched? I can see code, but in human readable format please.

[G-dH]

@meybonomme DtD's docking module overrides the same code as V-Shell does, including startup animation and overview allocation.

[meybonomme]

Thank you for the answer!

I have V-Shell dash module deactivated and other overlapping options are disabled from DtD settings. Probably that's why I don't have any noticeable compatibility issues between V-Shell and DtD. Or is there something else why to prefer patched version of DtD?

[G-dH]

@meybonomme V-Shell does a lot to mitigate potential conflicts, but at startup it's about the order in which both extensions are enabled. Which cannot be easily set, unfortunately.

[meybonomme]

@G-dH so your recommendation is to use patched DtD to avoid all possible conflicts?

[G-dH]

@meybonomme My recommendation is to not use DtD at all with V-Shell.

Sorry for the duplications, some error in my GitHub app..

[G-dH]

@Majo111 Are you still experiencing this issue?

[G-dH]

Feel free to reopen if you need.
