18.2 visual bugs
已回答
Just updated IntelliJ Ultimate to 18.2. It seems to have had a rendering rewrite, which is buggy on my system (Ubuntu 18.04 & NVidia 390 drivers, application installed via Snap, Dell 9560 with 4k monitor downscaled to 2k):
- Scrolling a source file (Java, TypeScript etc.) doesn't update the pane correctly and there is screen tearing
- Resizing panes has similar
- File search shows a blank search result box (class & everything search are both fine)
This didn't happen yesterday on same OS/drivers/etc. with 18.1. I've restarted my PC and cleared caches to no avail. The first tearing issue makes the IDE unuseable - I've had to revert to 2018.1.6 which works fine :(

FWIW there is also some old rendering bugs in both 18.1 & 18.2:
- Opening a modal screen (e.g. run configuration "VM options") still overlays other windows and isn't hidden when IntelliJ is backgrounded
- Debugging in IntelliJ messes up alt-tabbing/focus into IntelliJ

Hi, please provide idea.log (Help | Show log...)
Confirmed that's what I'm seeing too, repeatedly with very little else in the logs.
Same issue here as well and same error in logs:
Looks like https://youtrack.jetbrains.com/issue/IDEA-195614, Please try 2018.2.1 EAP: https://blog.jetbrains.com/idea/2018/07/intellij-idea-2018-2-1-eap-is-out/ (https://confluence.jetbrains.com/display/IDEADEV/IDEA+2018.2+EAP).
That resolved the issue for me, thank you
