You can check an update in the support ticket #1139253 that you opened for the same issue. I will post the reply from the ticket below in case there are any other community members experiencing the same issue:
"There is a known issue in build 18.104.22.1685 of our product, that is related to rendering the PictureBox contents on machines that have their DPI greater than 100% (96dpi). Based on the attached images, we guess that your reports may be affected by this bug, which is already fixed and will be included in a subsequent release of our product.
Please note that the issue is not reproducible when the machine DPI settings are set to 100% and we would recommend you to use this DPI when rendering your reports until the fix is published.
Another option is to downgrade to Telerik Reporting 22.214.171.1244 - this is an internal build and can be accessed from your account, as shown here."
Do you want to have your say when we set our development plans?
Do you want to know when a feature you care about is added or when a bug fixed?
