[Development] Requesting exception to feature freeze for lottietoqml

Hi, A new lottietoqml tool was ready to go (as tech preview) last week, but it needs a dependency update before we can actually merge it. The last successful update was May 23rd. It also introduces a Qt Quick type for supporting a specific Lottie feature, in a submodule under the Qt.labs.lottie

[Development] HEADS-UP: Qt Wayland will be frozen while migrating the QPA plugin

Hi! We are preparing to move the Qt Wayland QPA plugin into Qt Base where the other QPA plugins also live. This is required for us to run autotests on Wayland-based platforms, and it reflects that Wayland is becoming one of the standard display server architectures on Linux desktop. Overview a

Re: [Development] Why does QQuickImageProvider not support SVG images?

Hi, and thanks for the input! QQuickImageProvider is an interface that returns rasterized images and is very specifically for use with the Image component. It doesn't have support for returning encoded files in any format (it doesn't have any requestPNG() or requestJPEG(), and I don't think it

[Development] Minor cmake API change in Qt Wayland 6.8

Hi, We recently found an issue with Qt Wayland Compositor after upgrading to libwayland 1.23, which causes any Qt client to crash as it connects to it. To fix this, we need to add a small last-minute API addition to a cmake function in Qt Wayland Compositor: https://codereview.qt-project.org/c

[Development] Behavioral change with font metrics

Hi, I have a pending change which I would like to get into Qt 6.8 which will change default line heights of fonts in some cases, so I thought I would mention it here to hear if people have objections. Since it does change text layouts in some cases, it also adds a fallback mechanism to previous

Re: [Development] Replacement for QFont::ForceIntegerMetrics in Qt 6?

Hi! ForceIntegerMetrics was originally added to get CoreText to look at little bit better with WebKit, since WebKit did not support subpixel positioning at the time and CoreText did not support font hinting. I removed it in Qt 6 because it's honestly not a typographically sensible thing to do,

Re: [Development] QSGText: Why round glyph position like this?

Hi! Just removing the pixel snapping from the vertex shader should definitely cause regressions, yes. I'm not totally clear on what the problem is on your end, so maybe it is more efficient if you file a bug report for this with some screenshots and descriptions of what you mean? Eskil Abrah

Re: [Development] QSGText: Why round glyph position like this?

Hi! The reason for rounding is that the subpixel position of the glyphs is baked into the cached rendering of the glyph itself (so horizontal position x.5 would be a different cached object than x.0, but they should both be rendered at pixel x). It's a bit complex because the projected position

Re: [Development] QtWayland compositor can't to render a wl_surface to multi outputs, Is this a restrict of QtQuick graphics scene?

Hi, Each window has an isolated scene graph and RHI instance, which is the reason for this limitation if I understand correctly. Decoupling them is actually quite complicated, because different screens have different surface formats requirements and it might not be possible to render to both sc

Re: [Development] Does QSGPlainTexture needs call setHasAlphaChannel on Vulkan renderer?

Hi, If the texture does not have alpha, that means we can do disable blending, do front-to-back sorting to minimize overdraw, and use depth-buffer checks to preserve stacking. So in the case where you know there is no alpha, this is an optimization. If you do not know whether or not there is an
