Server sends COMMAND_SCREEN_PREVIEW_REQ when user double-clicks an active (non-Locked/Inactive) host that advertises CLIENT_CAP_SCREEN_PREVIEW. Client BitBlts primary screen, encodes to JPEG via GDI+ and replies. The existing STATIC tooltip is replaced with a self-drawn CPreviewTipWnd showing the thumbnail above the host info text, with wide-character rendering so the popup also works on non-Chinese servers. - Quality tiers reuse QualityProfile pattern: PreviewProfile + 6 levels driven by GetTargetQualityLevel (FRP-aware), with 4K/ultrawide auto upscale on Ultra/High tiers up to min(screenWidth/4, 1280). - Client limits to 1 in-flight capture via atomic counter to defend against flood/DoS; Send2Server is already mutex-serialized. - Server validates responses by reqId only (single in-flight tip); 4s arrival timeout marks "preview unavailable" without blocking the text fallback path.
