I’ve encountered an issue with Brave browser (Version 1.69.153 Chromium: 128.0.6613.85 (Official Build) (arm64)) on macOS Sonoma 14.6.1 using a dual-monitor setup. When using vertical tabs, clicking a tab in one browser window causes a background Brave window on the other monitor to unexpectedly come to the foreground.
This bug does not present with horizontal tabs.
Steps to reproduce:
- Open two Brave windows, each with vertical tabs enabled (Window A and Window B).
- Place each window on a separate monitor.
- Make Window A active on Monitor 1, and have a non-Brave app active on Monitor 2 with Brave Window B in the background.
- Click on a vertical tab in Brave Window A.
Expected behavior: Only Window A is affected.
Actual behavior: Window B on Monitor 2 comes to the foreground, covering the active non-Brave app.
If instead of clicking on the vertical tab in Brave Window A we click on the header bar or body, then we don’t get the aberrant behavior. It only occurs when clicking on an actual tab.
Has anyone else experienced this? Are there any known workarounds or settings to prevent this behavior while keeping vertical tabs? Thanks.
