I have a problem with the current version in a Linux container using 2024.1.30 and 18.0.24.305 version of reporting. I only get this when I'm attempting to produce multiple reports at the same time.  It's the same issue regardless of whether it's running as a hosted web service or if I'm running as a server based blazor app.

DockerBlazorApp Error: 0 : An error has occurred while rendering the report: System.InvalidOperationException: Operations that change non-concurrent collections must have exclusive access. A concurrent update was performed on this collection and corrupted its state. The collection's state is no longer correct.

When the input data of a pie chart is such that some of the series are insignificant enough not to be drawn on the surface area, a DocumentRenderException with the message "The operation was canceled" is thrown by the Reporting engine.

Enlarging the pie chart or hiding/removing its data point labels clears the error. 

If I use an HTML5-based Report Viewer with the default CONTINUOUS_SCROLL page mode and I start scrolling to the next page, the Get Document Page request is made multiple times for the same page.

If I move to the next page via the toolbar buttons or if I use the SINGLE_PAGE page mode, then problem is not reproduced.

If the password of the SQL user contains the percentage symbol (%) before a number, the last three steps of the SQL Data Source Configuration Wizard cannot be completed.

Hi,

HTML viewer is showing Arabic words correctly while PDF Export shows splitted characters.

Correct word :  فاتورة
Wrong word with splitted characters :  ةروتاف

Please find attached screenshots for reference.  The issue is appearing only with Linux container. 

Telerik support ticket (https://www.telerik.com/account/support-center/view-ticket/1623687) was created and got reply that it is because of libgdiplus library and we were expecting that this issue will be resolved in R2 2023 but it still persists.
