Here is an example of text issues I'm having with 2829. Attached files show screen shots of 2813 with OpenGL Enabled/Disabled and then 2829 running the same study with OpenGL Enabled/Disabled. Attached are screenshots and code to replicate the issue. Italic text with FW_BOLD does not render - Italic + FW_BOLD = FAILS - Italic + FW_NORMAL = works FW_NORMAL text with multiple DrawTextAt calls does not render - FW_NORMAL + multiple DrawTextAt = FAILS - FW_BOLD + multiple DrawTextAt = works Not sure if this is a coding issue or something related to the 2829 version. Thank you. |

Refer to: Important: Understanding Fonts and Text when using Open GL We should have a solution to the nonvisible text out next week. In general though you are going to want to avoid, using too many different fonts, and sizes because that will have a negative effect on performance. We recommend using one font face, when using OpenGL and only change its size, and other attributes like bold. Sierra Chart Support - Engineering Level Your definitive source for support.
