Hello,

With the Weather2 mod installed, I get reproducible screen flickering when my client is between 20-60 FPS. The greater the FPS the less severe the issue is. I have removed both CoroUtil and the Weather2 mod and the flickering immediately stops. I have tried testing to be sure it is these mods causing the issue and am confident they're the source.

Is there a particular config setting I can edit to stop this from happening? Is this a known bug in this particular version?

I'd like to use this mod in my pack but users are reporting the flickering is actually affecting them physically in some cases and that's not something I want to leave in the pack.

Mod Version: CoroUtil: 1.1.5 Weather2: 2.3.10
MC Version: 1.7.10
Forge Version: 1614

Thanks for taking a look at this,
Darkosto

Sorry for not getting to this soon enough, been paying less attention to 1.7.10 related issues once I started pushing to mc versions past that.

My biggest suspicion is how I manually modify the sky darkness to make it seem more localized, to see if that feature is the cause of this flicker, go into config/weather2/Misc.cfg and set Misc_proxyRenderOverrideEnabled to false

If that fixes it, let me know and I can refine the code more.

Also note, with that off, you will likely see both my rain particles and vanilla rain overlapping eachother and possibly some other unsual visuals, but this should do nicely for a temp solution.

I have been testing my mod with globalOvercast set to true to maybe make weather2 mod compatible by default and noticed the problem suddenly, currently occurring when server side rain/thunder starts or stops, though this only causes it to do this for 5-10 seconds then stops, so there might be other scenarios I am not aware of yet if it was happening non stop. I figured out what vanilla code is causing it, a solution is still in the works for 1.10+, might backport to 1.7.10 if it seems worthwhile to.

I'm experiencing the samething in my 1.10.2 modpack, but I think it's a cross mod thing on my end. I think it has to do with Harvest Festival and Weather2 trying to render over each other possibly.

Had some sudden inspiration and ideas about this, seems fixed for 1.10.2 and 1.7.10 now.

1.7.10: 8ce1962
1.10.2: 152eede

Builds have been pushed to curse for both versions.

How to reproduce for unfixed version:

• turn on global overcast
• run command /weather rain 9999
• run command /weather clear 9999

Fixed builds no longer reproduce it with steps above.

Sorry it took so long ;) quite an annoying issue too.

So far, I have not noticed a correlation between brightness and the flickering effect. I have seen it on multiple brightness settings.

what do you have your brightness set too at the time?
