@GyroPower Just create your render thread before you call Qt_wb_app_manager.exec();

@grainyblob Might be a weird question but I am quite new to coding, in the image, how did you get those rounded corners while applying acrylic? because I though corners were limited to 8px on windows 11 due to dwm, but it seems you have gone over this limit, I'm asking because I want to make a program that is similar to macos tahoe 26 spotlight search but for windows 11 using this effect.

@sierdzio Thank you a lot for your answer ! Your explaination on the opaque pointer is clear, I didn't have that notion before. With this knowledge, most of my questions are wrong, like the 5th.

@SGaist thanks for response. Assume we use http://www.openh264.org/, I guess we would compile it for our Raspberry Pi based platform. Correct ? Are there steps to configure QT (or underlying libs) to use newly compiled openh264 codec ?
