Description: Transitions that rely on OpenGL such as Fade, Iris and Circles do not work as expected. Rather they show a weird flashy effect. Steps to Reproduce: 1.Create a new Impress presentation with two slides 2.Insert text and objects in both slides 3.Apply the "Fade" transition to the second slide 4.Press F5 to start the presentation 5.Move from first to second slide Actual Results: The move to the second slide shows a weird effect, instead of the expected Fade transition. Expected Results: I expected the Flash transition without these weird flashing of the screen. Reproducible: Always User Profile Reset: No OpenGL enabled: Yes Additional Info: I posted a video on Youtube showing the transition effect: https://youtu.be/ocspMGvPHaY My computer runs Ubuntu 20.04 and I am using the PPA version of LibreOffice. I have a NVidia GTX 1660 video card. I also experienced this problem in all releases of the 6.4 branch. I am also testing the 7.0 beta 1 version and this problem keeps happening.
Could you give a try at: https://wiki.documentfoundation.org/QA/FirstSteps#Graphics-related_issues_.28OpenGL.29 ?

The "About LibreOffice" screen says "UI render: default". The option "Tools ▸ Options... ▸ LibreOffice ▸ View ▸ Use OpenGL for all rendering (on restart)" is currently checked. I tried unchecking it and restarting, but nothing changed. Shouldn't my "About LibreOffice" screen say "UI Render: GL"?

Did you upgrade your graphic card driver as indicated in the provided link? Could you attach <user profile>/cache/opengl_device.log ? Perhaps you use a graphic card blacklisted by LO for OpenGL use. In this case your pb is not OpenGL related.
Created attachment 161727 [details] OpenCL.log

I am running Nvidia driver 440.82, which according to Ubuntu repositories is the latest version. There is no "opengl_device.log" in my user profile. There is rather a file named "opencl_devices.log", which I attached to this report.
On pc Debian x86-64 with LO Debian package 6.4.4.2, I don't reproduce this. Version : 6.4.4.2 Build ID : 1:6.4.4-1 Threads CPU : 12; OS : Linux 5.6; UI Render : par défaut; VCL: gtk3; Locale : fr-FR (fr_FR.UTF-8); Langue IHM : fr-FR Calc: threaded Thank you all for your feedback. Since I don't have more questions, I'll put back to UNCONFIRMED. I must recognize I'm stuck and can't help here. => uncc myself.
