Created attachment 202291 [details] Example file from Impress with one master bg image set With some templates, such as Focus there is no default background fill set. This in turn causes some redraw issue when activating the Slide - Master Objects menu item: the shapes on the master slide are not turned off until I move to another slide and back. 1. Open attached file 2. With the first slide, use Slide - Master Objects -> This slides master has a background image, which will become visible and the colored triangles disappear - this is good. 3. Go to the second slide, use Slide - Master Objects -> This slides master has no background image or fill, so nothing happens 4. Go to the third slide, then back to the second slide -> The colored triangles have disappeared, as they should have in the previous point.

Created attachment 202293 [details] The second slide after turning off Master Objects The checkbox in the sidebar shows that Master Objects is now off, but the colorful triangles are still visible.
Created attachment 202294 [details] The second slide after going to another slide and back After changing slides the canvas is updated. Another issue is that the slide sorter on the left is not updated in any case.
