Graphical problem on Win11 Remote Desktop

[jaktherenegade]

Describe the bug
If you access a Windows 11 PC via Remote Desktop Connection, Cartool will no longer be able to display the EEG trace. In Cartool, the file window will open without error message and only the trigger/marker will be visible. No EEG trace will be visible.

To Reproduce
Steps to reproduce the behavior:

1. Install the last version of Cartool64 (5.05.00) on a PC which works on Win11 (version 10.0.261000 Build 26100)
2. Access to this computer with another one by using the Remote Desktop Connection tool of Windows
3. Try to open any EEG file with Cartool

Expected behavior
See the EEG trace and trigger as usual. This was working normally under Win10. It hasn't worked since our institution upgraded to Windows 11.

Hi,
Thanks for reporting...
This looks quite peculiar, as the windows does draw itself, and the triggers do show up, but not the tracks.
I used to use Remote Desktop on Windows 10, and had no issues. When you say "no longer", does that mean it used to work on a previous version of Windows 11?
Classical question: have you tried to upgrade the graphic card driver? has anything changed in terms of display?
