After the new PD4 launch am experiencing lot of display problems that turn my gaming experience annoying

Betting, either manual or auto, it's OK but site is constantly glitching (every few seconds) : monitor turns all grey (same kind of grey as the upper horizontal bar where deposit withdraw faucet buttons are located) for a second or so and then come back to normal.
This glitch (dunno if it's the correct term to use to describe this "bug") doesn't affect autobetting proper run.
Is it only me or anyone else s having same problems?
