Title I have decided to recapitulate all the bugs I have found all this time in just one post for ease of information.

Table

Issue Color Corners Fade Lines Noise Spots Other Issues Quality Time
1.3.1 Cold High Low Low Med Fixed Blocks remains Low 1:46
1.8 Contrast High Low Med Low Fixed Blocks remains Low 2:39
1.9 Contrast Med Low High High Grid Grid everywhere Med 2:50

3.6 Contrast High Noise Fixed Low High Max 13 mins aprox High 5:28

What does each error mean?

Issue Description Thumbnails
Color Dandere2x makes the color appear more contrasty than normal. Color
Corners In a scene with movement said with a little noise, white dots begin to appear in the corners of each block. Corners
Fade Does not change the illumination of the blocks in fade transitions, it was fixed in 3.3.1, but in 3.6 there is a similar error due to increased noise, it is not this because the Fade error is aligned with the grid. Fade
Lines This error appears in light scenes, such as plain yellow and white colors. It is difficult to replicate, but it is quite common. Lines
Noise It is the noise in the image, which is much more noticeable on TN screens. Noise
Spots By this I mean some dark borders that appear on the grid, that's what I thought, because it also happened that blocks appeared that did not change their color, being quite noticeable. This error is noticeable in video, not so much in image. Spots
Quality This is the quality of the final video. Quality
Time This is the time it took my computer to upscale the 15 second test. As the latest versions take some time before upscaling the frames, I only considered the time from the beginning of frame 10 to frame 350. Time
Other Issues Version-specific bugs are added here. Other

Observations

There appear to be no lines in 3.6, however I believe a very few appeared when upscaling the same video 2 times.

The "Spots" bug may be being generated in a similar way to the "block remains" bug, when small squares remained on the screen and did not change, since a small part of a heart remained on the edges.

All tests were performed with the maximum block and quality.
