Bug tracker for all OpenGL bugs
I think it's possible that bug 78703 https://bugs.documentfoundation.org/show_bug.cgi?id=78703 (SLIDESHOW: fading slide transitions start with a white 'flash) also belongs in this metabug.
I never noticed the "white flash" other then when using 3d slide transitions.
How is this not a duplicate meta tracker (see bug 93529)
nevermind I read the comments on the other one and I see the difference - although it's a bit hard for people without quite a bit of experience to really understand the difference. Are we sure that the bugs here shouldn't be on the other meta tracker?

That meta tracker is focused on stuff in 5.0 and above, while the bugs here are focused on all opengl bugs that were introduced/reported since the fork.
The comment on the other bug clearly thinks otherwise....but I'm not going to get into it. Having two meta trackers about the same issues is confusing. Removing myself from cc.
looks as if editing with a clumsy UI/slow connection made me remove lots of issues.. Readding now. Apologies!
added Bug 96328 - delay in appearance of text in dropdown menus and tooltips with OpenGL on

shouldn't this one be closed as duplicate of 93529 ?
I have been experiencing flickering transitions for a while in my PC, but today I had an important insight as to what causes it. In summary, it happens only with the VCL-Gtk version of LibreOffice. The video below shows the flickering transition bug happening on my PC.
The video was made using Ubuntu 20.04 (Gnome 3.36), thus with VCL-Gtk.
I had to format my PC and installed KDE Neon. After that I installed LibreOffice and took the opportunity to test if the transition bug was still there. And indeed it was still there... but then I noticed that the LibreOffice version installed was the VCL-Gtk one, even though I was on a KDE desktop environment.
Then what I did was uninstall LibreOffice and reinstall it using the libreoffice-kf5 package. After that, I tested the transition bug and it disappeared. All was working fine.
In conclusion, I tested LibreOffice using the same PC, the same DE (KDE Plasma 5.19.4), the same packaging source (the LibreOffice PPA), but I only changed the VCL version from Gtk to Kf5. And it fixed the problem on my computer. Hence, I believe that this may have something to do with the Gtk implementation of LibreOffice.
As a side note, the fade animations work well with VCL-Gtk, whereas transitions are buggy. I'm not sure if this means anything, but I think it is worth mentioning.
