DeepSeek PC clipboard paste lags (2026)
Paste a one-line test first.
Trim logs before pasting a stack trace.
Close extra windows if paste stalls.
Update the desktop client.
Note whether a reboot cleared the lag.
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.
