Thanks! That's correct, the dimming layer injected below a modal popup use an odd ClipRect value (due to ahem, reasons): I took the liberty to rework your commit into e8dd47e, matching the style and comments used by Metal, Vulkan and SDL_Renderer backends which need the same thing. Thank you! |

When opening a popup using Dear imgui, a grey transparent layer is rendered below the actual popup. This layer seems to have a size superior to the framebuffer size by a 1 pixel amount - which causes a crash in the wgpu backend one frame later.
Clamping the clip_min/clip_max to force them to be within [0, FrameBufferSize] is enough to fix the issue.
