Narrative:

Chronic problem occurring consistently for approximately 6 years or more.please reference report X for my most recent report on aircraft X; as well reference report Y for a similar chronic malfunction of aircraft Y and current actions from maintenance.on takeoff; I observed both the red minimum operating speed (red checker on speed tape) and yellow minimum maneuvering speed (yellow bar on speed tape) at speeds between 35KIAS and rotation; while on the ground. I also observed the same tapes after landing from touchdown to about 35KIAS while slowing. In both cases; those speed tapes should be inhibited while on the ground. This presentation occurred only on the first officer display and presented normally on the ca side. The discrepancy was written up after the flight.also of note is that prior to the previous leg a malfunction was observed with the first officer stall warning stick shaker not testing on the ground. It was cleared using [procedure X]. This is similar to aircraft Y. During their repair of that problem a discussion was had where one of the mechanics noted that there is a timer on the wow circuitry to prevent multiple on/off events from occurring with a bounced nose-wheel. He wondered if that might affect this weight on wheels problem. Per reply from [maintenance technician]; he felt this stall issue was related to the first officer's side of the plane not knowing it is on the ground; would also affect the inhibit function of the first officer speed tape features.as it appears to me this is primarily a failure of the weight on wheels functions of the first officer side and not necessarily a failure of the stall warning computer; as I believe that has been replaced previously.

Title: First Officer reported that he has observed a recurring problem with the Minimum Operating Speed and Minimum Maneuvering Speed speed tape indications erroneously appearing during takeoff and landing rolls.
