该问题出现在 Ubuntu 20.10 中。闪烁非常频繁。Conky 消失 1 秒并在桌面上显示更新。这种情况一直发生，并且与 CPU/磁盘使用情况无关。设置double_buffer = true没有帮助。
我正在使用 KDE v5.19.5。 （但同样的问题也发生在 Gnome 上），显卡是 Intel HD Graphics 4600。KDE 窗口设置中没有针对 Conky 的特殊设置。
答案1
问题出在配置文件的最后一行${voffset 5}${execi 10 tail -n8 /var/log/syslog | fold -w52}。每次/var/log/syslog更改文件时，Conky 都会开始闪烁。我通过保持功能不变来解决这个问题。首先，我编写了一个脚本来跟踪 syslog 文件，它会创建一个临时文件，其中包含 syslog 的最后几行并环绕文本。
#!/bin/bash
while true
do
tail -n8 /var/log/syslog | fold -w52 > ~/.conky_syslog_workaround.log
sleep 10
done
该脚本在登录时启动。然后我用新的一行删除了配置文件中提到的行。
${voffset 5}${tail ~/.conky_syslog_workaround.log 20 10}
现在工作正常，没有闪烁（从 Ubuntu 20.10 开始出现）。
