Trying to select blocks of text just... doesn't work properly. I can't select it in real time (visual lag), only random sections go to clipboard, and sometimes it just plain won't select at all.
This only happens in chromium (and derivatives) in timeless. Other browsers are fine. The skin also seems to make chromium weirdly slow in general for some reason; this may be related.
Er, this is on linux (mouse clipboard), Chromium 63.0.3239.84, and when running out of SWAP. Yes, SWAP can be slow, but not this slow, and not for this, as evidenced by other skins not being affected. Tested on meta.
Oh, also hardware acceleration is disabled, may or may not be related, but now we're getting into the general rabbit hole of chromium's utter instability.
This has nothing to do with SWAP. Probably caused by disabling hardware acceleration combined with some css chromium doesn't handle well?
...the underlying cause may have also changed. This is/was a chrome bug. It may now be a different chrome bug, as it was previously triggered by certain css rules, which may have... changed?
It is now also being triggered by the js modules as well.
Change 440246 had a related patch set uploaded (by Isarra; owner: Isarra):
[mediawiki/skins/Timeless@master] Remove nonfunctional jquery mobile stuff
General note that the above patch is actually resolving something totally different from the original problem that was causing this, but that may have been fixed upstream regardless. Or something.

I am not sure if this is resolved now? The patch fixes the issues I was having, but what you're describing actually sounds different.
I thiiink the other issue was resolved upstream, and somewhere at the same time the same effect that the patch fixes moves in to replace it?! I don't even know.
NOPE, STILL HAPPENING. Or again. Or something.
