Get XCB connection for QWindow

How do I get the XCB connection (xcb_connection_t*) for a given QWindow in Qt5? Right now I'm using QX11Info::connection() to retrieve this pointer, but that depends on libQt5X11Extras.so, which might not be available on every target system.…

WGSL: Multiplying a vec4f by a mat4f identity matrix produces different results

I am trying out WebGPU for the first time and have come across a problem. Normally in other rendering frameworks I would multiply a vec4 my a matrix of all 1s and the output would be the same. Here is what I expect with this code: @vertex fn…

How to time profile/see when tasks are complete in wgpu (targeting web)?

Basically title. There are support for timestamp queries, but that requires specific device feature support (my laptop for example does not support it when targeting web). There is also the function Queue::onSubmittedWorkDone(callback) that throws…

Max texture views accessible per fragment shader in wgpu-rs

I am working on a rendering engine in wgpu-rs. I have a system which "batches" rendering, splitting large amounts of vertices and textures into separate draw calls. However, I need to find out what the limit for textures is. For example, when using…
