Thanks for your interest in RadControls for WinForms.
There are some known issues related with standard controls like SplitContainer
controls. The reason for these issues is that the controls mentioned do not properly support transparency and therefore you should set their BackColor
explicitly in order to avoid visual glitches like flickering.
My advise in this case would be to try setting the BackColor
property of your TableLayoutPanel
to a color suitable for your UI and see how it will behave.
Please, let me know if this helps.
Thanks for your time.
All the best,
the Telerik team
