設置 GTK_IM_MODULE=hime 會導致 Aegisub 出現詭異的透明背景

[msparkles]

如下圖：

研究了很久才發現跟這個變數有關。大多數人出問題都是跟 xim，受影響的軟體有 gedit/gnome-calculator
但是我的其他 GTK-based 軟體都沒有這個問題（有測試安裝過上述兩位）

EDIT 1:
hime-env

有需要更多訊息的話，抱歉了，本人 Linux 新手，不確定甚麼資訊重要

[msparkles]

另外，Hime 似乎也沒辦法在 Aegisub 使用

[msparkles]

測試gcin同樣不行，ibus, fctix都沒問題（但是這兩個都不好用啊...）

[marktwtn]

@MG138 目前還不確定問題出在哪裡

不過這應該跟 Aegisub 是用 wxWidgets 開發有關，同樣的情況也會發生在 FileZilla 以及 Poedit 這些使用 wxWidgets 的軟體上

[xilwen]

這個問題在 Ubuntu 套件庫的 Audacity 2.4.2 也會發生，但 Audacity Github 上的 3.0.4/3.1.3 AppImage 就正常 (可能跟 Audacity 3.x.x 開始用自己修改的 wxWidget 3.1.3 搭 gtk2 有關？ launchpad 有類似問題(但為xim) 的回報 )

另外有趣的現象：如果用 GTK_DEBUG=updates /usr/bin/audacity 啟動程式， GTK_IM_MODULE= 在顯示更新區域的速度非常快， GTK_IM_MODULE=hime 則非常慢，背景和元件異常的部份永遠不會更新出應有的圖片；同樣 GTK_DEBUG=updates 用於 gnome-disks, pluma, ghex 的程式則沒有這個情形。

測試環境： Ubuntu 22.04, hime commit 7b4f332 (gcin 2.9.0+dfsg1-2build1亦同)
