tried plasma a year back and gave up because I couldn’t get the above setup to work (annoying lines appearing while typing) on three different laptops (125, 133, 150%). there was supposedly a fix (increasing line spacing) but that didn’t work for me. just checking in to see if some workaround came to light? thanks.
This One? if you look at the bottom you can see a plethora of patches. Still, if it’s continuing to be a problem for you, you must report it with the appropriate information if you want it to get patched.
This bug clearly doesn’t effect that many users, and some have reported it’s fixed for them.
So it’s important you make some noise.
