Eclipse IDE strange behavior [message #1829626]

Hallo.

I'm using eclipse IDE for Java Developers for a couple months now. But since a couple days, I get really strange behavior. This is what I get.

- When I startup eclipse, everything is normal. But when I export my project, the font in the package explorer changes. It also get's bigger, so some letters aren't readable. This is also the case for the settings, but not the settings navigation.
- Sometimes, the completion suggestions just stop working, for no reason at all. In the left-bottom of eclipse, I see No completions available. No matter what I change in the settings, the completions won't come back. When I restart eclipse, I have completions working again.
- Sometimes, I can't export a project. When I right-click on my project, and then click Export..., nothing happens. No window, no export, nothing. I need to restart eclipse to get it back working again.
- The completions menu is way to big, and sometimes takes up the whole screen, other times only a small vertical bar, from the top to the bottom, other times a horizontal bar, from right to left. It's very inconsistent.

I tried everything I could think of. I switched workspaces, deleted all eclipse data (.eclipse and %localappdata%), and I tried these versions of eclipse.
- 2020-6
- 2020-3
- 2019-12

This is getting really annoying. It gets to a point that I want to switch to another IDE, but no other IDE works good enough for me, except for eclipse, before all the issues.

I'm using windows 10.

Does someone know what's going on and how I can fix it? Please don't say that I have to wait two months for 2020-9...

There were some comments on this thread about recent versions of Windows doing strange things with fonts:

As for the failures, hopefully there are some clues (stack traces) in the Error Log view. Press the magnifying glass icon in the upper right and type "Error" to open that view.

I turned Use mixed fonts and colors for labels off and restarted eclipse, but the font in the package explorer still changes after I export my project.

This is the error for the completions not working.

Is it always triggered by Exporting a project? Is there a release far enough back where that doesn't happen, then?

I don't know if it's only triggered when I export a project. I do know that it's really inconsistent. One time I get it really fast, other times after half an hour.
Like I sad earlier, I never had problems before. The problems just appeared, out of nothing. I didn't update eclipse or updated windows or something like that.
