Description of problem: I'm not using this f19 machine a lot, so I'm not sure when it started happening, opening any file in emacs for X (gtk gui) and using scroll bars (mouse pointer - click and drag up/down) freezes emacs client, emacs process uses 90~100% cpu, and only killing the application helps. (no crashes, backtraces ...) Version-Release number of selected component (if applicable): emacs-24.2-18.fc19.x86_64 gtk3-3.8.1-1.fc19.x86_64 How reproducible: always Steps to Reproduce: 1. open emacs with some text file (long enough to have scroll bars) 2. click on the scroll bar and drag up/down 3. lock-up Actual results: emacs locks-up Expected results: no lock-up Additional info: For testing I removed my ~/.emacs and ~/.emacs.d

Same thing is happening to me. It took me a while to notice as I usually use the scroll wheel or keyboard to move around, but it's 100% consistent - any attempt to scroll using the scroll bar causes the window to stop responding. I don't see an increase in CPU usage. Nothing is printed to the console either, I normally launch emacs from a terminal window, but it happens when lauched from gnome-shell as well.
ok, tested it again, and first I thought it raises cpu usage when in focus (window), but while testing it to confirm I started raising cpu usage without focus too, so it sometimes uses more cpu, sometimes it is really low (this is all when it is "broken"/"locked")
