Some electron apps flicker

[Akronix]

• Electron version: Not applicable. Franz: 4.0.4, GitKraken: 1.9.1 Atom: 1.12.6
• Operating system: Ubuntu 16.04

Actual behavior

Apps based on electron flicker sometimes.

How to reproduce

Web view blinks sometimes within electron apps. Apparently, when they are doing "heavy" graphics tasks.
For example, try using Telegram inside Franz and look for a gif (for instance, "Ralph") using @gif inline bot. Screen momentarily flickers as you're scrolling though the gif lists. Curiously, it seems to happen only when Franz window is maximized ("full size").

I have experienced same momentarily flickers in GitKraken or, less often, in Atom.

Seem to be related to chromium because I can reproduce this opening WebTelegram in a chromium browser tab but not in Firefox.

Without a consistently reproducible example their isn't much we can do.

FWIW though I've seen this before on my app and I fixed it my not calling app.disableHardwareAcceleration() on macOS

If you are running with Intel graphics, you may be seeing the effects of an issue documented in chromium bug 606152.

[Akronix]

It seems to be related to that. I've being using the nvidia discrete graphics for some time now and I don't remember to have experienced any flicker again.

It looks like tiny horizontal lines. Here in Slack

Thanks for finding this @r4v5. I'm going to close this out since it looks to be an open Chrome bug, please subscribe to it there for updates.

Problem in chrome can be fixed by appending these arguments:

--disable-gpu-driver-bug-workarounds --enable-native-gpu-memory-buffers

Unfortunatelly passing same arguments to Electron based app (Mattermost) doesn't help. Are arguments taken into account in Electron app?

[ccnokes]

@novoj how are you appending those arguments? Like app.commandLine.appendArgument('enable-native-gpu-memory-buffers')? appendSwitch doesn't seem to accept arbitrary arguments so just thought I'd double check.

[novoj]

Directly to the commandline when running MaterMost application:

/opt/Mattermost/mattermost-desktop --hidden --disable-gpu-driver-bug-workarounds --enable-native-gpu-memory-buffers

[ethernomad]

Ran

discord --disable-gpu-driver-bug-workarounds --enable-native-gpu-memory-buffers

and now discord no longer flickers on my ubuntu thinkpad with intel graphics!

Cheers @novoj

Meanwhile I've upgraded to Ubuntu 18.04 and problem vanished. But because entire system was wiped, there are many things that could have affected the result (including MattermostMost/Electron upgrade). I can't verify your recommendation but nevertheless I thank you.

[betimbryma]

i still have the same problem on Fedora 29, i mean i use --disable-gpu-driver-bug-workarounds, but it's just interesting to see why this is still an issue.

[simform-solutions]

I am still facing flicking issue on macOS HighSierra 10.13.6 and Graphics .NVIDIA GeForce GT 710 2047 MB

Note: The App is frameless and has a transparent background

Using Electron version : 6.0.0
Expected behaviour was working fine on electron version: 4.2.8 but getting now as shown below in latest version

Please help:

@SimformSolutions I'm seeing this as well.

Have you found a solution for this other than downgrading? If not we should open a new issue for this particular case.

[bolatovumar]

I'm also experiencing this issue. See LN-Zap/zap-desktop#2938 for details (includes video). This started happening exactly when the project was upgraded from Electron v5 to v6.

No we haven't found any fix. I see this issue is closed. Is there a fix inbound?
