Hello All thank you for the swift replies, i have the last version of everything. Now understanding it is a bug, on some apps it comes on others it doesn't.
Windows 10, 32" 4k monitor, disabled second monitors, but i do enable it here and there, could be that indeed.
I've reset to a default non customized curtain theme, will see if it comes back, know knowing curtain could be the culprit.
Is there a way to help you guys understand this issue to fix it ?
