Description Eike Hein 2018-07-23 10:24:44 UTC

I use Plasma/Wayland with 2x scaling.

At logon, plasmashell comes up with 1x scaling and doesn't update when KWin sets the output scale to 2x. So I restart plasmashell to fix the scaling.

After restarting plasmashell, I then experience lots of wrongly-sized and/or pixelated theme elements. Until I kill the shell, delete the theme cache from ~/.cache and restart the shell.

Confirmed; still an issue. I see this in Wayland all the time due to Bug 433460.

Comment 2 Marco Martin 2021-03-10 12:03:24 UTC

there are 2 parts to this bug: one is plasma getting notified the new correct scale, and i think this is what still fails.
then there is a caching issue of the old stuff, which lately with svg caching refactor should have gotten a bit better

Apparently we tried to fix this in Bug 424615 which I forgot about, but there are still some things that need fixing before it fully works.

We shouldn't be flushing the cache on theme change. For the symptoms see 424615.

A comment some issues remain, but we have no content in any bug report that's actionable.
