Bug

Description

Sometimes when an IME panel is shown/hidden, some chunks of the old panel hang around and don't get cleaned up.

They flash as if we're alternating between two buffers and each glitch is only in one. (See video)

How to reproduce

Here's a minimal IME used in the video that shows and hides a red panel on alternating keypresses:

Can you update the corrupted video, please?

[q234rty]

Please reopen this: the artifacts still happen when pressing backspace while the popup is visible.

@q234rty Can you provide a video and the exact repro steps? Does the artifact look different from the video above?

[q234rty]

I'm outside so can't provide a video, the repro steps are just press backspace when fcitx5 popup is active so that the length of the popup decreases.

[sungyoonc]

Oops mirrorlist was outdated, updated and have reproduced it.
