Description of problem: When using the auto-complete function in a Jupyter notebook (using the Tab key), a menu appears to show options. Switching between different options causes Firefox to hang for about a second. Enabling webrender (gfx.webrender.all to true and gfx.webrender.enabled to true in about:config) solves this issue. Version-Release number of selected component (if applicable): How reproducible: always Steps to Reproduce: 1. open a jupyter notebook (e.g. https://jupyter.org/try) 2. start typing a command 3. press tab 4. use arrow keys to switch between options Actual results: firefox regularly hangs for about a second Expected results: smooth switching Additional info:
Can you try X11 version of Firefox (firefox-x11 package)? Also can you try mozilla binary with a fresh profile? How-to is here: https://fedoraproject.org/wiki/How_to_debug_Firefox_problems?rd=Bug_info_Firefox#Testing_Mozilla_binaries Thanks.
The Fedora X11 package, as well as the Mozilla binary in X11 mode work as expected. The Fedora Wayland package has the issues described above. The Mozilla binary in Wayland mode (MOZ_ENABLE_WAYLAND=1) has a slightly different behaviour. When cycling through the menu with the arrow keys, everything works smoothly. However, when using the Page Up and Page Down keys, the browser hangs as well.
Can you please give me more exact reproduction steps? I see that jupyter notebook for first time and I'm not familiar with any commands there or so. When I just type in the notebook the tab does not give me any option. Thanks.
Sure. A more detailed set of steps is as follows: 1. Open https://jupyter.org/try 2. Click on "Try Classic Notebook" and wait for it to load 3. Add a new empty cell to the notebook by selecting "Insert" -> "Insert cell below" 4. Activate the new cell by clicking on it 4. type "import " into the new cell 5. Press the tab key to open up the autocomplete menu 6. Use the arrow or Page Up/Down keys to navigate the menu
I do see that too, Thanks.

Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
