    Description

      Qt Creator starts to consume 100 % CPU shortly after startup (even if no files opened). I tried to disable plugins, reset settings, start the application as another user - no effect, the problem persists. But the application's GUI doesn't hang, I can do my work with it.

      strace log shows repeating lines:

      poll([

      {fd=5, events=POLLIN}, {fd=8, events=POLLIN}, {fd=11, events=POLLIN}, {fd=12, events=POLLIN}, {fd=22, events=POLLIN}, {fd=28, events=POLLIN}, {fd=34, events=POLLIN}, {fd=17, events=POLLIN}], 8, 0) = 1 ([{fd=12, revents=POLLIN}])
      poll([{fd=5, events=POLLIN}
