RDP security prompts can misrender on multi-monitor setups after April updates
Microsoft warns of a bug where the new security warnings shown when opening Remote Desktop (RDP) files can render with unreadable text and misaligned buttons when multiple monitors use different display scaling, affecting Windows 11/10/Server after the April 2026 updates. The prompt appears before connecting and shows signer status and resource redirections; the issue follows increased attacker use of RDP in phishing campaigns (e.g., APT29).
