i have the problem while testing fnc gantt chart. On VCL Project an youre samples if i move the mouse over the charts it starts to fliker (Refresh) the gant. On FMX and WEB the problem don't apprears.
I have record a video for showing the problem:
My installation:
latest fnc gant version; Delphi 12 with patch 1 on a WIn 11 Microsoft SurefaceBook 2
Are you using this via a Remote Desktop or a Virtual Machine?
As there are some known issues with flickering if you work this way.
But I'm not able to reproduce this problem on my system.
yes i use this system via Remote Desktop, i have tested direct and is ok.
I have clients with terminalserver or citrix heare i need a flicker free version ;-)
This is a known issue and this should be the solution based on the following thread:
You should set the TApplication.SingleBufferingInRemoteSessions property and set it to False.
