Post From: Strange lag when scrolling chart (only when viewing specific time period)

Hi, I noticed a very strange issue today which is unfortunately quite hard to describe: When I scroll my chart within a specific time period it's very slow and laggy. Strangely, this only happens when a specific time period is visible in the chart (to be precise today after 10:50 New York Time in the ES). When I scroll the chart to the left (so that none of the bars after 10:50 are visible anymore) everything is perfectly fine and smooth. However, as soon as I scroll to the right and the bars after 10:50 get into view, Sierra instantly becomes very laggy and almost unusable. I attached screenshots of my two charts in which this is happening. It seems that this issue is somehow related to the Numbers Bars study which I am using in both charts, because I don't have this issue in any of my other charts (where I am using plain candle sticks). I never had this issue before and as I said it is strangely only occuring for me in today's ES chart after 10:50. I double checked the ressources in my Task Manager and CPU / memory usage don't go up when I am scrolling within this specific chart area so resources don't seem to be an issue here (and I have a very strong computer, so the hardware shouldn't be an issue anyway). I also restarted (twice) and just installed the latest version, but it didn't fix the issue. This problem makes Sierra Chart unsuable for me right now, so no live trading for me during today's session. But any idea what this could be and how I can fix it would be very appreciated, so that I can hopefully trade again tomorrow. Update: Very strange indeed. I just returned to my computer after a short break, and the issue seems to only occur in a very small time period between ca. 10:50 - 11:30. When I scroll to the right and the bars before 11:30 are not visible anymore, the lag is gone and everything works fine again... Date Time Of Last Edit: 2022-10-17 16:17:38
