--- Comment #1 from Jonah Brüchert <[email protected]> --- The reason for the heigh CPU usage is that QR-Code scanning requires doing some image processing on every few frames that come from the camera. To reduce it, we could try to detect codes less often, but then scanning becomes slower. On my hardware it is not a noticeable problem though, and it is much weaker. Do you have a very high resolution camera by any chance? We currently already disable scanning in the background on systems that only display one app at the time (e.g phones), but of course it would be possible to add another case for a minimized window. Patches welcome. -- You are receiving this mail because: You are watching all bug changes.
