Picture display/browsing does not work properly when SmartRedraw is active (linux) about xbmc HOT 2 OPEN

The whole smart redraw logic (which intersects with dirty regions) is pretty broken, up to the point where I would say both are unmaintained and unsupported.

@sarbes that's kind of sad, I measured the power consumption results for smartdraw vs. non-smartdraw with the machine on idle and smartdraw achieves massive power savings: 6 Watts vs 14W on idle in an Intel N100. For always-on machines, embedded SOCs and the like, this is a grea features. It's also key for fanless as there is a large improvement in temperature as well.
Hoping that it will get again the focus it deserves.
The current state is not that bad, I use it every day on the family HTPC, there are a few glitches (specially in the video overlay when playing back content) but are tolerable, fully usable (benefits outweigh issues) - the only "big" problem for my family use case that got introduced in Kodi 20 is the total brokennes of picture browsing.
