Title:
image and footer jumping on screen change
Status in OpenLP - Worship Presentation Software:
Incomplete
Bug description:
As the footer and background image divs are set in the projection
screen as absolute position with 0 px top, on screen change the
background image and footer is jumping, as it first gets loaded and
displayed, and repositioned/rescaled afterwards, thus causing a visual
jump. Attached a screencast, which shows the exact problem (please
note that it does happen always, but the screencast doesn't show the
bug for all screen changes, only for some, because of the 15fps
framerate).
Another note: this affects Linux only with desktop environments having a top bar on the screen we are projecting to (e.g. unity on Ubuntu, doesn't happen with Gnome Shell)
As a workaround I have found that in openlp/core/lib/htmlbuilder.py removing the position, left and top css attributes from .size solves the problem, however causing the image to be cut off at the bottom, but for me at least this is an acceptable price to avoid the more visible visual jump. (there's still a small issue with the footer jumping, but I will investigate that, or at least can workaround by setting the footer font size to 0)
