International Ski Federation race director Guenter Hujara said course workers would try to slightly lower the jump ahead of Friday's second training.
"It's very difficult there. We can't take it down too far," Hujara said. "We have helpers on it and we'll see tomorrow morning."
More racers were unhappy with course conditions for the opening training, in which Hannes Reichelt of Austria posted the fastest time ahead of Italians Dominik Paris and Christof Innerhofer.
After overnight snowfall, the icy course was partly covered by spots of soft snow.
"It's tough, mostly due to the conditions," Aksel Lund Svindal said. "It's icy at some places and there are a lot of places where there is still a lot of bad, fresh snow that shouldn't be there. They'll have a lot of work to do on that."
The Norwegian, trailing leader Paris by three points in this season's World Cup downhill standings, expected a tough race.
"There's not that much gliding," Svindal said. "There are so many rolls that it doesn't feel like gliding."
Reichelt came down the 3.3-kilometer course in 2 minutes, 2.98 seconds. Paris was 0.11 behind and Innerhofer, the 2011 silver medalist, trailed Reichelt by 0.35.
Guay and Svindal finished fourth and fifth respectively, while last season's World Cup downhill champion Klaus Kroell was sixth. The rest of the field trailed Reichelt by more than a second.
A second training is scheduled for Friday, followed by the race on Saturday.
The course will be shortened on Friday as training takes place in between the two runs of the women's super-combined, which uses the same finish area.
