Ubuntu: ZKL lags massively when opening new chat tabs; randomly closes

[Histidine91]

It drops my desktop UI to what feels like 5 FPS. When starting up ZKL this can last for several minutes.
Also it randomly closes itself (I can't even tell if it crashed or not).

This didn't happen a couple of months back.

Running on Ubuntu 14.04 LTS

probably related to really stupid player list updates...

when ZKL close itself in Ubuntu, it meant it crashed. (There's no "ops, send crash report?" pop-up IMO. )

First step is to get ZeroKLobbyErrors.txt and see if its an easy bug to fix.

FATAL: System.NullReferenceException: Object reference not set to an instance of an object
at System.Threading.Timer+Scheduler.SchedulerThread () [0x00000] in :0
at System.Threading.Thread.StartInternal () [0x00000] in :0

Find where System.Threading.Timer is used instead of System.Timers.Timer it should be just 2-3 places one of them is it.

I found 1 here: https://github.com/ZeroK-RTS/Zero-K-Infrastructure/blob/master/Shared/PlasmaShared/SelfUpdater.cs#L15

Do we need to replace it with Timer.Timer?
But it wrote: System.Threading.Timer+Scheduler <--- what is the "+" mean?

@Kingraptor says the "Steam DLL not found" exception still happen to him regularly, I remember @Licho1 said ( http://zero-k.info/Forum/Thread/11631#119478 ) it was fixed.

oh, if was fixed in "welcome_screen" https://github.com/ZeroK-RTS/Zero-K-Infrastructure/blob/welcome_screen/ZeroKLobby/Steam/SteamClientHelper.cs#L46

I didn't get Timer error in my Ubuntu 14.04.1 LTS
Mono 3.2.8 (Debian 3.2.8+dfsg-4ubuntu1)

Can't confirm low fps because I don't have good driver in Linux, I always low fps

@Licho1 can I copy https://github.com/ZeroK-RTS/Zero-K-Infrastructure/blob/welcome_screen/ZeroKLobby/Steam/SteamClientHelper.cs#L46 into master?

[Licho1]

I think it should be merged somehow im not sure what happens if you do that to auto merge ... no idea..

[xponen]

If I copy paste, I will fix conflict manually by updating welcome_screen with master. Like I did before with local_replay!

after manual merge, no more problem.

[xponen]

okay merged!

I add 2 new commit, hopefully it fix it when deployed later:

fix for steam.dll not found spam

Tried running from terminal:
"TASC channel joined: " messages come several seconds apart, even if the channel is completely deserted (and the client is lagging the whole time while the channels are being joined)

Is this still a problem?

[Histidine91]

I don't recall any random app shutdowns lately, but the lag was still a thing when I last used it on Ubuntu (within the past month)

[Licho1]

This should be fixed by special catches for steam library uncatchable exceptions
