brave starts slooow

[arvindautar]

Description:

Brave Browser consistently takes ~60 seconds to start when KDE Wallet is disabled on systems running KDE Plasma. Re-enabling KDE Wallet eliminates the delay, indicating Brave may be attempting to interact with the wallet subsystem and failing ungracefully.

Steps to Reproduce:

Use a Linux system with KDE Plasma (version below).

Ensure KDE Wallet is disabled (via kwalletmanager or ~/.config/kwalletrc).

Launch Brave Browser.

Observe a long startup delay (~60 seconds).

Enable KDE Wallet again and relaunch Brave.

Startup is near-instant.

Expected Behavior:

Brave should handle the absence of KDE Wallet more gracefully, without introducing long delays during startup.

Actual Behavior:

Startup is delayed by approximately 60 seconds when KDE Wallet is disabled.

Notes:

This behavior is reproducible and confirmed to be resolved immediately when KDE Wallet is re-enabled.

If KDE Wallet is disabled (e.g. Enabled=false in ~/.config/kwalletrc), Brave shouldn’t try to connect to kwalletd6 at all. If the check isn’t feasible up front, at least the D-Bus calls should fail fast — right now they hang for nearly a minute, which blocks the whole startup.

Possible duplicate of #34889

[zeusshomaly]

I disagree, but they should work on a RAM limiter to limit RAM whilst gaming and that'd help lots of users to make RAM faster.

[arvindautar]

Re-enable KDE Wallet Manager:

Go to: System Settings > KDE Wallet

Check "Enable the KDE wallet subsystem"

Create an existing wallet with no passwords stored.

Set it to auto-close and not open at startup.

This satisfies dependent services without storing sensitive data.

Confirmed: enabling KDE Wallet (with an empty wallet set to auto-close) resolves the startup delay. Thank you @iT-hub-cloud — that workaround works perfectly.

[arvindautar]

Still, this seems like a fragile dependency. When kwalletd6 is not running and KDE Wallet is disabled (e.g. Enabled=false in ~/.config/kwalletrc), Brave attempts to access it anyway and hangs for ~60 seconds. The delay is clearly linked to unhandled D-Bus calls to the KWallet subsystem.

Ideally:

• Brave should not try to interact with KWallet at all if it’s explicitly disabled.
• Or it should fail fast on D-Bus errors rather than blocking the whole startup.

This behavior is identical to what was discussed in #34889, but it’s still reproducible today (Flatpak version 1.78.102, KDE Plasma 6.3.5 on Fedora Kinoite 42/Aurora). Feel free to close this if it's considered a duplicate — just wanted to document the full chain of cause/workaround.

Thanks again!
