Details

(Keywords: nightly-community, regression)

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:122.0) Gecko/20100101 Firefox/122.0

Steps to reproduce:

I'm using KWin/X11. This is a continuation of Bug 1865739.

Same STR:

  1. Move the mouse to the corner that triggers the Overview (which presents all open windows in current virtual desktop).
  2. Select a Firefox window to focus on it. Make sure it's in a position that the pointer will be over Firefox afterwards.

Actual results:

The cursor sometimes changes for a fraction of a second to a resize icon.

Expected results:

This seems to be a regression from Bug 1813554.

A similar (same?) issue with the same regressor:

  1. Grab the scrollbar.
  2. Move the pointer to the corner of the screen while, still, holding the scrollbar.
  3. Move the pointer over the browser and release it.

The cursor remains stuck at the resize icon button.

:emilio, since you are the author of the regressor, bug 1813554, could you take a look? Also, could you set the severity field?

I forgot to mention that the titlebar needs to be disabled: browser.tabs.inTitlebar:1.

Can't repro on wayland at least, fwiw.

The issue in comment 1, occurs on X11 only, but the initial I verified it occurs in Wayland as well.

Severity: -- → S4

Possibly the same issue. STR:

  1. Open a URL, not an internal page.
  2. Grab the scrollbar and move the cursor over the upper window edge until the resize cursor is shown.
  3. Move the cursor over a blank area of the content page.

AR:

The cursor stays to the resize icon until you hover over something that should change it.

The builds are old and thus deleted, so mozregression cannot point to an exact commit, but it seems likely that this is the same issue, and it's a lot easier to reproduce.
