<div dir="ltr"><div>The rationale explained in the bug by Pekka and Emilio sounds OK to me. Explaining a bit more about your use case with your data visualization app might be helpful.<br><br>What kinds of systems do you want your app to be run on? Generic desktop systems? If so, then you can't guarantee anything about utilizing hardware overlays, as the user might be watching a video at the same time, which should take HW overlay priority over your application to prevent a YUV -> RGB conversion in software.<br>
</div><div><br></div>If you have a special usecase like a Bloomberg terminal, then making your own shell and shell protocol like the IVI team is doing might be a better solution, so you can guarantee window position and HW utilization. The default desktop-shell is very much designed for desktop Linux use cases, where we don't want to expose global window positions or make any guarantees to the client about where they are on screen, precisely so you don't assume you are the only user of the HW.<br>
