Your statement which I highlighted (bold) above was important to me. That was my biggest concern. I could not see any discernable difference or drop in quality, but it's always good to get a confirmation from someone with your knowledge & know-how on these matters. 

I do understand your point about bug reporting and I will ultimately open this up as a different thread for those reasons. 

One quick pointer though, which I omitted in my original post. 

I have a "Client" / "Satellite" HTPC which I use in the family room to stream media & games (Steam IHS) from the main Home Theater HTPC. The above issue & specs were for the main Home Theater HTPC. 

The "Client" HTPC has simpler hardware - Intel Core i5-2500K CPU & nVidia GT 1030 GPU. This machine was also upgraded from Krypton to Leia at the same time, and Client/Server setup was configured between the two. Very interestingly, this system does not have the Render Method issue. I'm able to set Render Method as "Auto" and Allow Hardware Acceleration - DXVA2 to "On" and video playback is perfectly smooth & flawless. 

This video playback issue only occurred on the GTX 1080 machine - the main HTPC. This tells me that it's not simply a matter of Kodi v18 - Leia "requiring" Software Rendering Method & DXVA2 "Off", or that it's unable to function with those features - but rather, quite possible, a mix of circumstances. Or perhaps, Leia is not at fault at all in this issue - since it works perfectly fine on my much lower-end GT 1030 machine. Perhaps it's something else altogether on my main HTPC. 

I'm not sure. But it is good to know I don't need to lose sleep over PQ.
