Hi, This series fixes running a modifier-aware server with a non-modifier-aware DRI3 compositing manager. We'd thought of and dealt with the case where we had legacy/non-modifier-aware clients, but slipped up with non-modifier-aware compositing managers.
Glamor would allocate pixmaps with the full set of modifiers available to it from GBM/EGL, then try to export them to a non-modifier-aware client. This may fail outright (e.g. when the modifier adds a plane), or result in garbage (with an exotic modifier selection the client can't infer via magic back channels). When we get a request to export a buffer to a non-modifier-aware client in Glamor, forcibly reallocate it with no explicit modifiers, so we get something that can be exported to legacy clients. Cheers, Daniel _______________________________________________ xorg-devel@lists.x.org: X.Org development Archives: http://lists.x.org/archives/xorg-devel Info: https://lists.x.org/mailman/listinfo/xorg-devel
