Please state your Qt version. Also can you run the attached case with qmlscene from comment #1 here. https://bugs.kde.org/show_bug.cgi?id=386846 and tell me if you get an error there. finally can you run kscreenlocker_greet with both QSG_RENDER_LOOP=basic and =threaded qt is still on 5.9.2 according to https://bugs.kde.org/show_bug.cgi?id=386846, errors appear also with qt 5.10.5. My peculiar problem can be worked around by killing the vnc session and restarting the vnc server. Then (without logging in at all) the cpu consumption is about 10% (on a 16core machine), so this is ... quite ok for me at the moment... The reference to 5.10.5 was for the Plasma version. Qt only released version 5.10.0, and you would need to test this version. Dear Bug Submitter, This bug has been in NEEDSINFO status with no change for at least 15 days.

I have a similar problem on a regular X server without VNC. kscreenlocker_greet's CPU load is somewhere between 15% and 50% most of the time (these are percentages of 1 hyper-threaded core capability). OS: Fedora 28 Plasma 5.13.5 Qt 5.11.1 KF 5.52.0 (In reply to Alexander Potashev from comment #6) > I have a similar problem on a regular X server without VNC. > kscreenlocker_greet's CPU load is somewhere between 15% and 50% most of the > time (these are percentages of 1 hyper-threaded core capability). > > OS: Fedora 28 > Plasma 5.13.5 > Qt 5.11.1 > KF 5.52.0 Shall I create a new bug report for my case? Search bugzilla first, there's a thread where switching to the software renderer fixes it. You probably meant https://bugs.kde.org/show_bug.cgi?id=347772 Well, can't reproduce at the moment, will report next time I detect high CPU load. Thanks! That's the one. Report back if it helps or not, I might try and automate the detection. |
