Priority: medium Bug ID: 65514 Assignee: dri-devel@lists.freedesktop.org Summary: Mesa can't render Google Maps WebGL preview in Firefox Severity: normal Classification: Unclassified OS: All Reporter: nmiell@gmail.com Hardware: Other Status: NEW Version: unspecified Component: Drivers/Gallium/r600 Product: Mesa

Both current git Mesa (8bc788ea9e73ef4c355dfea80ac5070c6f81ac1c) and current Fedora Mesa (mesa-libGL-9.2-0.7.20130528.fc18.x86_64) fail to render the preview version of the WebGL based Google Maps correctly in Firefox.

The Google Maps preview renders correctly in Chrome using Mesa and in Firefox using Catalyst.

The misrendering occurs with both RS880 (Radeon HD 4250) and JUNIPER (Radeon HD 6770) GPUs.

After the initial map is rendered (when in Map mode), Firefox fails to update the map in response to user interaction (dragging the map around, searching for locations outside the current map view, zooming, etc.) unless the window is resized.

If you switch to Earth mode (which uses aerial photography instead of line drawings), in addition to failures to redraw, forcing redraws using resizing often results in corrupted rendering.
