That symptoms is known for KDE in 25.2.3. New for me that it's also for
Gtk3 (at least I assume that you use Gtk3 based on the info below).

I tried now and I was able to insert a .mkv in Impress and play the
presentation just fine.

Are you also using the nvidia binary driver? Or above firmware with
nouveau? (Disclaimer: I am not using nvidia and will not do so)

Here it is
07:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Cezanne [Radeon Vega Series / Radeon Vega Mobile Series] (rev d1)
without any extra driver.
