i'm constantly getting double characters when typing on linux. it seems to be to do with the autocomplete popping up and then disappearing. afaik this only started happening with 2026.1. i'm running on a remote desktop.

Hi Christopher,

Please try disabling all downloaded plugins via Settings | Plugins | ⚙ | Disable all downloaded plugins, then restart the IDE and check whether the issue persists.

Also let me know:

  1. which remote desktop software you are using
  2. whether the problem happens only in the Editor, or also in places like Terminal, Find, or Replace
  3. whether the IDE and project files are both on the same remote machine

If possible, please also send:

  • a short screen recording
  • IDE logs collected right after reproducing the issue via Help | Collect Logs and Diagnostic Data
  • the output of xev -event keyboard from the same remote desktop session after pressing one key once

As a quick test, please also try disabling inline / full-line completion in Settings | Editor | General | Inline Completion and let me know whether that changes the behavior.

i think maybe it was caused by a bug in the Full Line Code Completion plugin, as that updated a couple of days ago and I think it's stopped happening.

hmm actually it's still happening, but seemingly not as often
