1015262 - BasicCompositor does not copy intermediate mShmImage to widget when HAVE_SHMIMAGE on OMTC linux with GTK3

Status: RESOLVED INVALID

(Core :: Graphics: Layers, defect)

Description

[Frederic Plourde (:fred23)]

When Enabling BasicCompositor for OMTC linux GTK3 with layers-use-image-offscreen-surfaces enabled (see bug https://bug1015218.bugzilla.mozilla.org/attachment.cgi?id=8427796) and GTK3 implementation of nsWindow::StartRemoteDrawing() (see https://bug1015211.bugzilla.mozilla.org/attachment.cgi?id=8427786), OnExposeEvent does not get fired perdiodically anymore, but still does on gtk menubar click, for example. So when content changes, the user needs to click on the window to refresh the widget's content.

no, the block/depend flags may be removed from both bugs.

This bug no longer applies now that further discussions in bug 1015218 have uncovered some misunderstandings. I'm closing this as INVALID, since the description points to OnExposeEvent while the root cause was in fact related to GetThebesSurface not properly returning an gfxXlibSurface for GTK3 widgets in non-OnExposeEvent cases (like when you Ctrl+ in the browser to scale content) and this has been properly fixed by Bug 1013552.
