Explorer Dark Interface Flashing White

WinSCP Version 6.5.6 (Build 16502 2026-03-25)
Dell Pro 14 Plus PB14250 (newly built about a week ago)
Windows 11 25H2 Enterprise

SFTP
Explorer

This started when I built my new laptop, about a week ago.

Every 60 seconds or so, the left (folder nav) pane and subfolder/file pane go blank white during what looks like the content panes referesh. The "flashing" takes 2-3 seconds and is very distracting. The setting to refresh the remote is not checked.

Never mind. We use DisplayFusion Pro v10.1.1 (an older version), and when I close it, the WinSCP panels no longer flash white.

I'll see if I can get the latest release of DisplayFusion and see how that goes.

Thanks.

Thanks for sharing your findings.

Out of the box, the latest DisplayFusion (12.0.2) had the same effect. Disabling "Multi-Monitor Taskbars" in DisplayFusion fixed WinSCP.

I've tried to reproduce the problem with DisplayFusion, but I could not.
Even with enabled DisplayFusion "Multi-Monitor Taskbars" (which disables Windows "Show my taskbar on all windows"), I do not see any flash. Do you have the dark mode enabled system-wide? Or just in WinSCP? Does the flash occur in the dark mode only (or does it just make it more noticeable)?

I unchecked "Enable Multi-Monitor Taskbars" in DF and the flashing returned in about 60 seconds.

• System wide dark mode.
  
• The flash happens w/ WinSCP Light Mode, Dark mode, or Automatic mode.
  

Unchecked or checked? Previously you wrote that you disabled the "Multi-Monitor Taskbars" to fix the flash.

Unchecked = disabled

Sorry, I've read it as "unchecked ... Multi-Monitor Taskbars" – I've missed the "Enable".
