Description

Have you tried it with Fedora 15 beta? Sorry for the late response. It was quite tricky to find a program to test this in F15: most of them are not yet ported to GTK3 and so they are still linked against GTK2. That means that they can't be compiled against F15's clutter-gtk (which is linked against GTK3). Finally I have found "gnibbles" from gnome-games-extra: "gnibbles" shows the reported issue in F14 (it only works with CLUTTER_VBLANK=none), but it works (at least somehow, it was quite slow) in F15.

I have now re-tested the problem with gthumb (compiled against clutter-gtk010): F15: works F14: does not work, window content is not updated unless CLUTTER_VBLANK is used This doesn't look to me at all as a xorg bug. Reassigning to clutter for further investigation. (In reply to comment #5) > This doesn't look to me at all as a xorg bug. Reassigning to clutter for > further investigation. It doesn't happen on any other card, clutter doesn't have card specific issues so it must be card/driver related. It might be kernel DRM driver related. Does this kernel fix the issue: * Tue May 03 2011 Dave Airlie <airlied> 2.6.38.5-23 - radeon updates from 2.6.39 with cayman + fixes for lots of things including Fusion. - vblank fix for core drm *** Bug 710795 has been marked as a duplicate of this bug. *** (In reply to comment #6) > It doesn't happen on any other card, clutter doesn't have card specific issues > so it must be card/driver related.

Sorry, it looks like I forgot to mention it in this bug report. However, since I have updated my only system where I could reproduce the problem to F15, I can't reproduce the issue anymore. However, it looks like that the issue is still there in F14 (see recent duplicate). |
