+Subject: [PATCH] loader/dri3: Avoid freeing renderbuffers in use
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Upon reception of an event that lowered the number of active back buffers,
+the code would immediately try to free all back buffers with an id equal to or
+higher than the new number of active back buffers.
+
+However, that could lead to an active or to-be-active back buffer being freed,
+since the old number of back buffers was used when obtaining an idle back
+buffer for use.
+
+This lead to crashes when lowering the number of active back buffers by
+transitioning from page-flipping to non-page-flipping presents.
+
+Fix this by computing the number of active back buffers only when trying to
+obtain a new back buffer.
+
+Fixes: 15e208c4cc ("loader/dri3: Don't accidently free buffer holding new back content")
+Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=104214
