Debian 中非常奇怪的文本

Debian 中非常奇怪的文本

我拥有一台带有 KDE 的 Debian 笔记本电脑。有时,在我关闭并重新打开笔记本电脑后,文本开始显示如下: GIMP

直到我重新启动计算机后,文本才会恢复正常。此问题仅影响这些字符:cgnpqtEFM13589@|:并且它似乎只影响一种字体。我还注意到粗体字母受到的影响不同:

火狐浏览器

另外,上图中所有奇怪的 o 都完全相同(也许我的计算机以某种方式切换到另一种字体或其他字体?)。这个问题没有影响我的桌面(也有 Debian 和 KDE)。我有什么办法可以解决这个问题吗?

字体是 DejaVu Sans,但它似乎并不影响所有 DejaVu Sans 文本(例如,它不影响 Firefox URL 栏)。

答案1

对我来说看起来像是视频卡问题。如果您使用闭源驱动程序,请尝试开源驱动程序(反之亦然)。尝试升级 Xorg,尝试在 KDE 中切换 3D/硬件加速选项。尝试使用 Xfce4 和其他字体也可能值得一试。
