If bo->width doesn't match fb->width the driver fails to configure the display correctly, resulting in a scrambled display. This little series has a patch for vram, to store bo->width (1/2), and the actual bugfix (2/2). The other drivers using the vram helpers are probably affected too. Reproducer: Run gnome-shell in wayland mode. It'll round up the bo dimensions to a multiple of 64 (for tiling I guess). Somewhat odd display resolutions will reproduce the bug. Example: An 800x600 framebuffer will use an 832x640 bo.
