What device do you use?

This happens on a 2018 15" MBP. I can reproduce this by dragging the telegram window onto a secondary screen, then dragging it back to the laptop screen.

Also worth noting that the Close, minimise and maximise buttons disappear when the window is inactive after dragging to a secondary monitor.

It flickers in time with the text cursor blinking. No flickering occurs when there are no active text fields. One way this can be achieved is by opening settings.

As already stated, the problem resolves itself after completely restarting telegram.

I have the same issue... Any progress on this? MacBook Pro 13 Inch early 2017 and using an LG screen as a second monitor - the flickering happens on both my mac and my LG screen

I have same issue too. Im using macbook pro 15 early 2015

I have the same issue. I have a MacBook Pro Mid-2014 running macOS Mojave Version 10.14.4

When I connect to an external display and try to drag Telegram to the new display. Telegram is blacked out. On my primary display there is a slight flicker in assets like the Avatars and other images. This issue goes away when I restart Telegram with the secondary display connected.

I'm using a display port adapter connected to a VGA Dell Monitor.

I've similar issue on imac 4k. It mostly happens on main screen but sometimes also on external ones.

Same issue, Mojave 10.14.4, MacBook Pro (Retina, 15-inch, Mid 2014), moving mouse over Telegram app produces flickering. Yet when I just resized the Telegram window it's not happening now. I move it around, nothing. I close it an open it again, still no flickering. So I drag it off to a second screen and the flickering is back. Drag it back to the primary screen and flickering is still there. Resize the window and its gone.

Update. This issue does not seem to affect me on the flowing configuration:

Operating System: macOS Mojave 10.14.5 (18F132) Version of Telegram Desktop: 1.7

I have the same issue on MBP 2018 13' with touchbar. Here is a video of the problem:

Same issue for me -- moving latest Telegram (1.7.3 as of now) on OSX Mojave 10.14.5 from primary to secondaty monitor make it flicker on every mouse move above the Telegram window. Like window.onmousemove = () => window.flicker().

And yes, resize resolves the issue.

@askoretskiy Hopes for 10.15 :/

[maxkuzkin]

Same here with Telegram 1.7.3 (latest of now) and OS X 10.14.4 (18E226)... Not sure why and how and when this appeared, but is getting quite annoying lately. The only temporal workaround i've found is to disable all animations in Telegram - this way it only flickers when i move mouse on top of the application window...

[john-preston]

@maxkuzkin I hope 10.15 will fix that. Did you try updating to 10.14.5?

[maxkuzkin]

@john-preston, i've installed 10.14.5 (18F132) overnight and after reboot the issue indeed does NOT reproduce... Not sure if it fixed it or the reboot temporarily hidden it - will keep you posted here. Telegram Desktop is the best desktop messenger i ever used, would be great to not have that flickering anymore! :)

[maxkuzkin]

No, unfortunately, after 1-2 days of work the issue is back, just like before... 10.14.5 (18F132) doesn't fix the problem.

Yes, this started happening to me again. 10.14.5 did not fix it.

[joctabio]

I have the same issue also on Macbook Pro 13 early 2013 with macOS Mojave 10.14.4 and Telegram 1.7.7.

[maxkuzkin]

I've recorded how it looks on my macbook: https://vimeo.com/343106191/cfd9b48fe6 It doesn't happen to any other window in the system, only Telegram... There must be something different in what Telegram Desktop is doing that causes that. Even if the bug is in Mac OS, other desktop applications are not having the same issue...

[alexesnsk]

Same problem: Mojave 10.14.5, second monitor: Dell retina. If move app back to laptop's screen - there is okay.

[olegborzov]

Durov, fix this annoying bug, besit!

[botten-ct]

Switching the window to another screen temporarily fixes the issue. You can even switch it back immediately. The flickering will be gone for a while.

[joniler]

Same issue. Any pending solutions, or is this more BS with Apple's CRAP Metal 2 drivers?

[yangcheng]

I have a similar issue. Tried to switch between different color theme, did not help. The window on macbook's monitor is ok, flickering about once per second on external display

Same issue in 10.14.6 Telegram build: 1.8.8 Theme: Night mode

I'm using additional monitor

Guys its really annoying problem, please fix it ASAP!

Mac Book Pro Late 2013 retina, 1.8.15

[predatorpc]

Seems problem solved for me. I've installed Telegram from AppStore and its good for me.

[maxkuzkin]

I have latest Mac OS 10.15 with all updates installed and Telegram 1.8.15 (latest too) installed from App Store. And the problem is still here. Like before not every day but when happens => the only way to fix is to restart the App. I already have a hotkey on my Mac to restart it. :-)

[Tolga-GA]

Guys, come on already! Fix this flicker issue!

[meleshuk]

I saw the flicker before, but it became worse recently. Does not reproduce deterministically, but inevitably starts flickering after a few attach/detach external monitor cycles. Flicker is slow like "trying to attract attention" notification. 1.8.8 on 10.15.1
