This fixes an issue where copying text would break until changing
workspaces and consequently windows.
This *was* fixed in 0.32.0 as a result of [1], however kitty 0.33.1 with
the recent fontconfig workaround patch[2] ends up showing CJK characters
with a very thin weight, causing them to be inconsistent relative to the
surrounding text and more difficult to read.
