Rendering Lag with Ubuntu 20.04 LTS for OBS 25.0.8, but less for 25.0.3

Hello,

I was using Ubuntu 18.04 LTS and never had this problem. Then installed new 20.04 LTS and OBS 25.0.8.

I get a lot of lags, ca. 3-9% and the video does not play smoothly. I tried everything described in the net. There is no "overload" as I am just capturing VHS tapes. The CPU is around 10% and the GPU is a Nvidea GTX 1060 with 6 GB. It happens with both, NVENC or X264, but less with X264.

However, it cannot be the hardware, because I then installed OBS 25.0.3 and the lag drops down to 0.3-1.2%. Still sometimes the video is not smoothly, but much rarely than with 25.0.8.

However, I did not have these problems with older version of OBS with Ubuntu 18.04 LTS. I do not want to go back. There should be a solution with OBS. Maybe where can I get older versions of OBS to try them out?

...it improves while setting the bufferr manually with x264, CBR, buffer: 8000000. But still there is no complete elimination of this and I am around 0.4%

I have a new observation. If the screen locks due to inactivity and then I log back in, this makes about 1% of rendering lag. There is none as long as the screen is active, just when screen lock...
