rogue harbour epileptic zone

Happens usually when there are a lot of people in the rogue harbour, and i click on my stash(although not necessary, sometimes it'll happen as soon as i enter the zone) it has been happening for several leagues now, and i cant find anything about it anywhere that has a solution, the best "fix" ive had is changing my lighting and shadow quality to default, but this has only reduced it from happening 80% of the time down to about 50%, even though i have a powerful pc and can run many other AAA rated games on it with no issues.

many thanks and hopes on fixing this issue.

Same here. GGG support, please highlight this issue internally. It is really not fun to see those artefacts.
