--- Comment #22 from Tobias Deiminger <haxti...@posteo.de> --- I can now reproduce the issue (CPU 30%, pages no more rendered, but okular symbol shown) in Ubuntu 19.10. But: For me it happens only if strace is attached to okular while scrolling through a PDF (the one from bug 39613). The issue then remains after detaching strace, it will never recover, and can be observed by attaching gdb. I see that QEventLoop is no more going to sleep, because the underlying poll() system call is always called with a timeout of 0, and that generatePixmap is called at high frequency while TextPageGenerationThread::isFinished == 1. Can't go on for today, but seems like a good position to continue debugging upcoming days. Albert, could you try if the "strace trick" helps to reproduce the issue at your side? -- You are receiving this mail because: You are the assignee for the bug.
