[Bug 546033] New: Avoid slow render path to accelerate composited windows on ATI Fglrx.
http://bugzilla.novell.com/show_bug.cgi?id=546033 Summary: Avoid slow render path to accelerate composited windows on ATI Fglrx. Classification: openSUSE Product: openSUSE 11.2 Version: Factory Platform: i586 OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: X.Org AssignedTo: bnc-team-xorg-bugs@forge.provo.novell.com ReportedBy: eich@novell.com QAContact: xorg-maintainer-bugs@forge.provo.novell.com Found By: --- Created an attachment (id=321952) --> (http://bugzilla.novell.com/attachment.cgi?id=321952) Alternative Fix. When (re)allocating the window pixmap for an composited window the Xserver copies the content of the underlying Windows to this pixmap as a backround to provide some reasonable background content in case this window has the Background=None attribute. This causes a screen2screen copy to be performed which seems to take a slow path on fgrx. The background in background=None windows is undefined. A patch proposed in https://cvs.fedoraproject.org/viewvc/F-11/xorg-x11-server/xserver-1.4.99-don... thus just comments out the copy routine (and produces a potential memory leak). The patch furthermore creates a security risk as the offscreen space may contain other meaningful content which may become visible again. If at all I would propose a different patch. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
