1. What is this called (for a better topic title)?
2. How do I prevent it from freezing my CPU*? I believe it's the transparency effect that's actually causing the freeze, as some other transparency effects in different applications also rarely freezes my CPU, but hovering over 4-5 of these truncated list items will freeze with a very high probability. It took me over 15 minutes just to make this screenshot.
* A 'CPU freeze' is a freeze of one of the cores for 60 seconds (until some kernel watchdog takes control and resolves it). Because it happens so very often with these transparent hover effects, my work efficiency drops to 1/20th at times. Sometimes it freezes for much longer (I've had it freeze for 6 minutes and 9 minutes) probably because mouse movements were still being recorded and played back after one freeze was over, causing serial freezes.
Solutions I'm looking for:
- A setting/registry to disable it,
- A setting/registry to disable the transparency effect,
- A setting/registry to increase the delay (which is now near-zero).
What I'm not looking for:
- Turning off the date/size info (as this freeze also happens with directories and in e.g. the thread list),
- Changes to OS or PC. At the risk of making this an X-Y question. I run Linux and I have an nVidia GPU. These are known to be mortal enemies.
Version of IDEA doesn't matter, it's not a bug in IDEA after all. I am open to working with any version between 2020.1 (i.e. downgrading) and EAP, if that matters.
