Latics boss Paul Jewell was furious with the performance of referee Eddie Ilderton who gave a number of puzzling decisions.
The first-year ref denied both sides clear penalties, and more annoyingly, awarded QPR a corner moments before their equaliser when the ball had clearly gone out of play off one of their own players.
Jewell fumed: "I thought he was out of his depth and I'll probably get into trouble for saying that.
"It was a blatant goalkick before their goal, although saying that, we didn't clear the corner he gave instead.
"We should have had a penalty and they should have had a penalty, but he upset us more than he did them."
The manager confronted Mr Ilderton on the pitch as the sides trooped off at the final whistle, but resisted the temptation to go and see him in his room later.
"If I had done that, I would probably have ended up before the FA again," he said.
But Jewell was keen the referee's display was not the only talking point from an entertaining clash.
A 29th minute free-kick from the recalled Andy Liddell put Latics in front, before Andy Thomson levelled the scores on the stroke of half-time.
Jewell said: "We didn't get the breaks out there, but we're not going to feel sorry for ourselves.
"We should have won and again we've ended up with a point.
"Of course we're going to have to turn these draws into victories, but we're still on a smashing run at the moment.
"The players deserve nothing but credit as far as I'm concerned because we were better than QPR, and QPR are a decent side."
Goalscorer Liddell was recalled at the expense of Gary Teale after a three-match suspension and two more sat on the bench.
Jewell admitted it had been a tough call to drop Teale, but felt the change had paid off.
"It was difficult to bring Andy back because Tealey has done okay out there," said the boss.
"I thought QPR would play a different way and that Andy would get more joy with them playing three at the back.
"But they caught us out by playing a 4-4-2.
"Andy still got a steady stream of crosses in, and I don't care if he meant the goal or not.
"It was a good quality free-kick and we always tell the players to aim for the far-post because if everyone misses the ball, it often goes in.
"I played Lids out wide because Neil Roberts and the Duke have done well up front.
"While it took him a while to get into the game, in the second half he was excellent.
"He's got the ability to cross the ball from tight angles and crosses early."
