fcitx5 is causing telegram to freeze

cjc7373 commented 11 months ago

Describe the bug I've done a quick search in fcitx5 and qt's issue tracker and didn't find anything. I wonder if I should report here or qt's side.

To Reproduce Steps to reproduce the behavior:

open telegram
type anything
the telegram window freezes

Desktop (please complete the following information):

Desktop: KDE 5.27.8, qt 6.6.0
Display server type: Wayland

Additional context

backtrace of telegram

wengxt commented 11 months ago

can't reproduce, what's the distro you are using?

Also as a way that will not trigger this code path: unset QT_IM_MODULE, select fcitx5 in the system settings -> virtual keyboard https://fcitx-im.org/wiki/Using_Fcitx_5_on_Wayland#KDE_Plasma

it will use wayland input method protocol instead

Also as a way that will not trigger this code path: unset QT_IM_MODULE, select fcitx5 in the system settings -> virtual keyboard https://fcitx-im.org/wiki/Using_Fcitx_5_on_Wayland#KDE_Plasma

This helps, thanks!

wengxt commented 11 months ago

where do you typed that triggers the freeze?

(You can try to reproduce with QT_IM_MODULE=fcitx telegram-desktop )

cjc7373 commented 11 months ago

In the chat, the search bar, the edit contact modal, basically anywhere..

The faster I typed, the more possibility freeze will happen. Randomly type about 20 characters would 100% reproduce the bug for me.

wengxt commented 11 months ago

I still I can't reproduce it here, is your system fast or slow? do you have an extremely fast key repetition rate?

wengxt commented 11 months ago

Also did you see "QWaylandShmBackingStore: stalling waiting for a buffer to be released from the compositor..." in the console?

cjc7373 commented 11 months ago

is your system fast or slow? do you have an extremely fast key repetition rate?

The issue happens after I upgraded qt to 6.6, so I'm pretty sure there's nothing to do with my hardware.

did you see "QWaylandShmBackingStore: stalling waiting for a buffer to be released from the compositor..." in the console?

No.

Anyway, since there is a workaround and it seems unset QT_IM_MODULE is the recommended way under wayland, I think maybe this issue can be closed.

fcitx / fcitx5-qt

fcitx5 is causing telegram to freeze #47
