Description
Issue description
Google Chrome UI changes when Quick Cursor is enabled:
- https://github.com/micku7zu/QuickCursor/issues/2 -✅ Fix available
- Address bar doesn't hide on page scroll
- Tab switcher animations are disabled
- Swipe down on address bar to open tab switcher is not working - This is actually a Chrome bug, because it actually works randomly (aprox once in ten attempts)
- "Undo Closed Tab" Message Timeout (it will increase to 30 seconds)
What happens
Chromium based browsers (Google Chrome, Brave, Vivaldi, etc) automatically detects when touch exploration or an accessibility service that can perform gestures (like Quick Cursor) is enabled and automatically changes the UI to adapt for accessibility needs.
It doesn't let the user decide if they want to UI to be adapted for accessibility needs, Chrome automatically makes this decision based on what accessibility services are running.
There is no way for me as a developer to exclude Quick Cursor from that check, Chrome doesn't have any exceptions, it checks for any accessibility service that can perform gestures on screens.
Chromium source code
You can find the method that detects the accessibility service with "canPerformGesture" permission or touch exploration on Chromium source code website. File ui/android/java/src/org/chromium/ui/util/AccessibilityUtil.java, method isAccessibilityEnabled()

But why other accessibility services don't have the same effect?
Because Chrome checks for any accessibility service that have the permission to "simulate a touch on the screen". Not all accessibility services needs or have this permission, but Quick Cursor needs this to simulate the tap at the cursor position.
