Title: Flashing 3ds max window when rendering
Post by: 1equals2 on 2018-03-26, 19:38:06
Hello,
Recently updated 3ds max to 2018 version. With particular scene, consisting of several Forest Scatters and quite big area for scattering, we tend to get quite slow loading/saving times.
The most disturbing issue is that  at certain moment when Corona is rendering this scene, whole 3ds max starts flashing, leading 3ds max to become non responsible.
Same also happened to a Vray scene, but less often so far. For the record- so far have used win 7 and 3ds max 2016, and never experienced any similar problems.
Has anyone experienced such issue?
It might be due to  old GPU/drivers/ win10/3ds max combo, but  we expected this to happen quite often, whereas it does happens, only when rendering at high res, and one can not save  file or render, due to the "flashing" 3ds max.

For the record - system specs:
Xeon 2680v4 x 2
Asus mainboard with built in video controler
Nvidia GTX 760
1050W PSU
850 W UPS
Win 10, Latest Forest pack, 3ds max 2018, Corona 1.7 (fix 3)
Dual Monitor combo with different Resolutions

Did this fix the problem? Several of us have been having this to. Randomly suddenly various max windows will start flashing like mad and it's pretty much impossible to get max to wake up again, so we lose the render/scene. Only happens during rendering...

Going to try this fix and see if it helps. Thanks!

For me, run max as administrator and reinstall Microsoft Visual C Runtime Librarie fix the problem.

Thanks for suggestion.

Have not tried to tackle the issue with  the method suggested.
Managed to  cope with it by disconnecting  the second monitor form the combo. So far so good.

The problem started appearing, as soon as tried to remotely connect to the machine via teamviewer and   saving elements while Corona still rendered. Definitely something with win10, since have same issue with Vray on a completely different scene and project.

Will post update about it during the week.

This happenens to me if I do render over night and turn the monitors of and turn them on again in the morning. This behavior begun when I installed all the service packs for max 2016. It's seems to be a max issue. I just dont turn of the monitors or if I forget, then connect via teamviewer and save the stuff before turning on again. Overall the service packs introduced lots of bugs to me :(

Sorry to dig up an old topic, but I’m having this issue with the latest stable build, Windows 10, Max 2020 and my new 3970x machine I just finished building.  I’ve tried the C++ runtime fix to no avail.  Had anyone found a definitive cause and/or solution?  It’s been driving me crazy.

Thanks!
Daniel

For anyone who finds this thread later, I believe I’ve found a solution to the issue.  It’s been mentioned elsewhere on the forum as a solution to issues other than flashing windows (Mostly slow interface), but disabling Control Flow Guard in Windows Defender (or creating an exception for 3ds Max) solves the flashing windows for me.  At least so far.

I feel like a post about this could almost warrant a sticky since it’s related to high threadcount and everyone is going towards threadrippers.  If you don’t know about it, solving it is a real time suck.
