Thank you Trevor for your valuable comments. For clarity, I present a real fragment of the scheme from my TV. I checked all elements in the horizontal deflection system. I also did a lot of tests with inserting subassemblies with slightly different values. The vertical glitch on the left side was not affected. Only increasing the capacitance of C2 resulted in an extension of the disturbance.
What I also considered was:
heavy damping symptom - this may be the cause of the changes on the oscillogram that I showed earlier. However, the image then tapers to the left but does not wrap
rings - there may be white stripes on the left, but probably without wrapping the image
slow flyback - may cause the image to wrap !. I don't know how to test it yet.
