ADDITIONAL INFORMATION
Comment 1 Olivier AJ 2021-04-27 18:49:03 UTC 
Issue fixed.

Root cause was not Kdenlive, but Xorg, who load the free libglx.so, instead of NVIDIA proprietary driver 

Extract from /var/log/Xorg.0.log with issue:
[     8.701] (II) LoadModule: "glx"
[     8.724] (II) Loading /usr/lib/xorg/modules/extensions/libglx.so
[     8.805] (II) Module glx: vendor="X.Org Foundation"

Extract from /var/log/Xorg.0.log with issue fixed:
[   870.828] (II) LoadModule: "glx"
[   870.828] (II) Loading /usr/lib/xorg/modules/linux/libglx.so
[   870.833] (II) Module glx: vendor="NVIDIA Corporation"
