Created attachment 132297 [details] Empty presentation with single Checkers slide transition The attached presentation is an empty file with Checkers slide transition on the slide. Open and play it (if your Impress is compiled with GTK3 support, start as: "SAL_USE_VCLPLUGIN=gtk ./soffice --impress"). About 1/3 way through there is a white flash. Observed with v5.1.0.3, 5.3.1.2, 5.4 master build / Ubuntu 16.04. Not reproducible with v5.0.0.5. => regression There is a bit of resemblance to bug 95479 and bug 99685, but they don't seem to be related.
Regression introduced in range: https://cgit.freedesktop.org/libreoffice/core/log/?qt=range&q=ba90813d17cf35cfb67585d6f119d3ddb30f5978..fe88fe6f828597fe2645a20c1a07716216a810c3 bibisected with lo-linux-dbgutil-daily-till51
Interestingly I don't get a flash at that point in the bibisect repo, so I looked further, and the range for me is this: https://cgit.freedesktop.org/libreoffice/core/log/?qt=range&q=41379970e8c6b75563b7c162b4e760b9e93a5bea..3a906cedeb700ffb950b46e728b20676956cec72 (2015-11-14: source-hash-3a906cedeb700ffb950b46e728b20676956cec72)

I would assume the issues are different, though.
Removing keyword bibisectRequest as it's already bibisected.
Works in 6.2.0.3, since 6.0.0.3 / Ubuntu 18.04. It was still buggy in 5.4.0.3. => Closing as WFM.
Reverse-bibisected the fixed behavior to the following commit. Nice fix, Jan-Marek! https://cgit.freedesktop.org/libreoffice/core/commit/?id=52dfefec8da5d7f25c39218fd890cad6491728ab author Jan-Marek Glogowski <glogow@fbihome.de> 2017-01-27 23:40:11 +0100 committer Jan-Marek Glogowski <glogow@fbihome.de> 2017-07-13 12:10:27 +0200 Run LO scheduler only via system timer
