A couple.
First is the Ty the Tasmanian Tiger run, which was sort of a halfway repeat of the Crash 2 incident. The runner was very nervous and disorganized, completely disregarded the Pacifist Run donation incentive and instead donated 1$ per enemy killed (what a penalty). Somewhat worse, he just sort of ignored a donation comment from the game's developers and his comments about the game's programing faults were more spiteful than lighthearted. I say a halfway repeat because, while the GDQ organizers more or less said they would never invite him back, they didn't throw him out of the convention, go full Internet Tough Guy threats on twitter, and get his Twitch shut down like with the Crash 2 runner.
The second cringe was just an hour ago, where the "Trials Ascend community speedrun" was not a speedrun and more of a boring, mostly silent 1 1/2 hour long ad by people who were at least wearing Trials Ascend shirts. I'm not sure what their involvement with the game was, but it was maybe the worst thing I've ever seen at GDQ. They also went overtime.
On the good side, GDQ appears to have backed off some on their bland corporate sanitation direction. They're still not allowing swearing per se, but anything PG-13 gets a pass and the streamers who have dropped F-bombs so far have just been asked to not instead of them freaking out about it.
On that note, this GDQ also has the single best speedrun I've ever borne witness to, which was Bonesaw's Jak and Daxter 100% run. The tech was fairly regular, but what made this run was that it was graveyard shift and consisted of Bonesaw and his couch going steadily insane alongside the GDQ staff, everything going wrong but still proceeding, and Bonesaw kind-of-sort-of twitter bombing AirCanada.
They also played the whole game in Japanese for a donation incentive.The Deus Ex run was on point, as was the Tetris Block though they aren't coming back to GDQ until Tetris Grandmaster IV finally re-emerges from the vaporware. The Momodora 1-handed run turned into a feels trip, and there have been a couple of WR near-misses.
All in all, I think GDQ could finish turning itself around from January's all-time low if things continue at this pace. I was ready to swear them off, but as long as they learn from those mistakes I'll give them a chance.
