Is anyone else seeing a bad lag issue with the CAN Monitor built into Service Tool when it is set to display in fixed positions? It appears to have been introduced with version 12.1 and affects all versions since.
You can see this when you switch to fixed positions the message display starts to lag. The display is getting updated for each received message but it takes several seconds to display one seconds worth of updates. When a value in a message changes it takes several seconds for the change to update on the monitor.
If you leave it set to fixed positions for a couple of minutes then switch fixed positions off it accelerates through the messages to catch up, that is several seconds worth of messages get displayed in under a second until the time stamp catches up.
It feels like the messages are not being retrieved from the buffer fast enough for display when set to fixed positions then when fixed positions is switched off it is able to run through the buffer quickly and catch up.
