Might be a respawn bug, ive had it happen a couple times when i die in a pw it causes my screen to bug out for a good 3 seconds before it respawns me. Could be that + timing out before respawn, or a completely unrelated issue. Timing out happens when something isnt allowing a stable connection between u and the server, its not an easy fix.
- Reset your router, unplug it, leave it for 5 mins, replug it.
- It could be an antivirus ig, maybe disabling any antivirus is worth a try.
- Also consider trying a client such as lunar/badlion (100% allowed on every server, nearly everyone uses them) as they may help with the screen glitching respawn bug. Note they will not fix ur connection problems and therefore you will still time out.
