So... I'll let you tell me what this is...

It appears as though a mess forms on my screen where the ground disappears and it only shows the background. This is very game breaking... could someone explain this?

I am using a 4k display with an nvidia gtx 960m.

So I had just leveled up my seraphynx and shortly after I was disconnected from the game. When I logged back on I saw that my seraphynx was back to level 14 but it had still used the catalyst, any way to fix this?

EDIT : Lost a spark of life too :^(

here the screenshot for the problem pls help me

I'll try to be as detailed as possible. So basically my PC broke down and I got a technician to transfer all my files to a new computer. He did so by moving the hard drive from one computer to the other. The new computer has two hard drives now, the new one being C: and my old one being renamed E:. Now the old hard drive still has all my files, steam, spiral knight everything (I use Spiral knights with steam btw). I opened Steam and updated everything but now when I try to run Spiral knights, it doesn't load even though it said everything updated correctly.

I had opened three frosty presents before this trade and got a windup key, a shoulder booster, and a headlamp. SK please fix this, this is not fair at all that our stuff can just get deleted. http://forums.spiralknights.com/en/node/113019

Whenever I play SK, it runs smoothly for a few minutes, then all of a sudden, it closes. This always happens, there is no set location for it to happen. Someone help me please.

~3.5GHz, 32652MB RAM,
Windows 7 Professional 64-bit (6.1, Build 7601) Service Pack 1 (7601.win7sp1_gdr.151019-1254),
NVIDIA GeForce GTX 680,

while I am playing, my character will lock rotation, making it so that I am unable to spin. this occurs on all movement modes. I have found that pressing esc will unlock this, however this posses a problem when you are in a large fight and have to kill menders.

i have bought the Fang of Vog with 40 Almirian Seals. But when i equip it, instantly i got disconnect from the sever and when i log in back, i lost 40 Almirian'seal with the Fang of Vog. Please help me GM, i have been doing this for months.

Well, on Win7 Spiral Knights worked perfectly, but when I've updated Windows to Win10 - Spiral Knights not working.
Steam opens Spiral Knights, but when I'm choosing character - app closes. But sometimes character loads, then trying to do something - app closes!
HELP!!!!
(Was trying to play SK not on steam - no changes; Trying to update Java - no changes; Trying to update gr. drivers - no changes.
And the worst thing, that I can't get back to Win7, because month is already passed.)

I am trying to make SK go full screen, but the client fails to do so and crashes.

How can I fix this problem?
