Description Nigel Cunningham 2007-12-17 14:20:51 UTC
I've just updated to current Xorg git, and everything works well (thanks for your great work!) apart from the fact that when a new region (if that's the right term) of the screen is drawn, you see a black flash before the contents are drawn. This is most noticeable when opening menus, but appears everywhere. I briefly tried using a composite window manager and didn't see the same effect (as I expected), but since this is an RS480 lappy, I have to wait for the textures-being-misrendered bug to be fixed before I could really treat that as a workaround. I'd love to give you a screenshot, but am not really sure I could hit printscreen fast enough. Instead, please just imagine opening a menu and briefly seeing a big black rectangle of the appropriate shape before the contents appear :) I'm assuming this is Radeon specific - I don't know for sure.

Did you also update to the latest xserver?  If so it may be XACE related.
Comment 2 Nigel Cunningham 2007-12-17 15:01:28 UTC
Yes. I recompiled everything using the script you guys supply. I'll attach the Xorg log - perhaps that will help.

Second version of the patch, ignore first version.

I think it's the same bug as in 13683. Unfortunately patch (either of them) doesn't fix issue for me.
