Flameshot: KDE freezes when copying to clipboard - still happening

[noraj]

Flameshot version

Flameshot v0.6.0
Compiled with Qt 5.12.1

Installed via AUR

Describe the bug

After a screenshot is taken, I click on the copy to clipboard button (flameshot gui) and the whole UI freeze.

I'm forced to change TTY and kill the process.

This is what appears during the manipulation:

$ flameshot       
QPainter::begin: Paint device returned engine == 0, type: 2
QPainter::setRenderHint: Painter must be active to set rendering hints
QPainter::setCompositionMode: Painter not active
QPainter::translate: Painter not active
QPainter::setPen: Painter not active
QPainter::setBrush: Painter not active
QPainter::setBrush: Painter not active
[1]    13645 killed     flameshot

I don't think #161 is related, but #389 may be and #170 seems to be exactly the same problem as me.

The weirdest things is that it is not systematic.

I can copy to clipboards tons of time nothing happens and then another copy to clipboard and it freeze, and when it start freezing and can kill and start it back it will freeze each time.

To Reproduce

I don't know what to say more than the description.

Expected behavior

No crash obviously.

System Information

Manjaro with KDE.

$ uname -a
Linux manji 4.19.45-1-MANJARO #1 SMP PREEMPT Wed May 22 17:16:41 UTC 2019 x86_64 GNU/Linux

$ plasmashell --version
plasmashell 5.15.5

Update: this is very annoying to have to switch to a TTY to kill the flameshot process.

Happens same in Manjaro for some time on XFCE

Flameshot v0.6.0
Compiled with Qt 5.12.1

Linux Carbon 5.2.11-1-MANJARO #1 SMP PREEMPT Thu Aug 29 07:41:24 UTC 2019 x86_64 GNU/Linux

Flameshot freezes whole UI after doing ANY action (even cancelling capture). The only way to unstuck this without killing flameshot process is to switch to TTY and back again to xorg

Works flawlessly under ArchLinux, but Freeze very often under Manjaro. I disabled Flameshot and I use Spectacle for now.

The same happens to me (Ubuntu 2020.04, pretty new installation). Anyone found a solution for this?

Check out issue #635 which is probably related. I'm not using KDE at all, which may be my problem in openSUSE Tumbleweed.

https://github.com/lupoDharkael/flameshot/issues/635#issuecomment-625276332 solved my problem. Thanks!

If #635 resolves the issue then the newer 0.8.x release will resolve this issue. It was a race condition related to notifications and DBUS. Please report back if it happens again. Thanks!
