DeepSeek PC window loses focus mid-type (2026)
If keystrokes vanish mid-sentence, check for overlay apps and notification toasts.
Disable always-on-top tools briefly to confirm they are the culprit.
Update the desktop client; older builds mishandle focus with multi-monitor setups.
Try a single monitor profile once, then re-enable the second display.
Smoke-test with a short prompt after each change.
Change one variable at a time and confirm what actually helped.
If a company policy is involved, rule that out before chasing client settings.
Write the working steps into a short checklist for next time.
Export or screenshot a good setup so reinstalls are faster.
If it still flakes, retest on a clean network such as phone hotspot.
