Not sure why but the IDE goes blury unless youre constantly moving or scrolling through the IDE.
Anyone else have this problem? Any help would be apreciated.
Your topic has been moved to the dedicated IDE 2.0 category on the forum.
I have not experienced your problem; which theme are you using?
I was using a dark theme, but even with the default white theme it was going blurry. I have now switched back to a 1.8.19 build and it stopped. Maybe its a problem with the new build and not my computer? Would be nice to find out why its doing that.
Alternatively, try updating the graphics card drivers on your computer. Changing the scaling settings in the operating system settings can also help. If the problem persists, try using a different version of the Arduino IDE or a different Arduino development environment. Also check if there are too many programs or processes running on your computer that could slow down the IDE.
1.8.19 IDE fixed the issue. Just for info; I tried updating graphics card drivers, Java, no issues with processes.
Thanks alot for your answer.
IDE 2.0.4 does not use Java 
Ah I see, thanks for letting me know!
I am getting this issue too on one PC, the scaling is set at 100% and the screen is set at native resolution. The text appears clear immediately, then sort of blurs out over the course of a few seconds.
I've played with some display settings but can't seem to improve it, is there any other setting i can check?

I don't have an answer to your question @Lesthegringo, but I am interested to know which operating system you are using. I can see from the screenshot that @chineseletters was using Windows.
Hi there, thanks for responding
It's a windows 10 OS, and the Arduino IDE is the latest version.
Cheers

When I looked I couldn't find any fixes online or anything and I also had win 10 and latest IDE. In the end I just downgraded and it fixed everything.
I have the same issue. Windows 10 build 1709. Graphics card is Nvidia GeForce GTX 1060. I'm running native resolution on two monitors, one at 1920x1080, the other at 3840x2160. The IDE does the same thing on either monitor. Tried switching off Clear Text and that was no help. I guess I'll try an older version. Wonder what features I lose in doing so.
You can try turning "Anti-aliasing - FXAA and transparency" off in your graphic's card configuration. It did the trick for me.

I have the same problem, blurry window, researched it a lot, tried same as you. Win 10 Geforce as well (GTX1050 Ti), i7 16Gbyte. Pretty irritating. Arduino is the only app that does that. It could be GeForce problem?
Hi @rfaass. Were you able to solve the problem by using the technique described above by @fpomini? If not, I can suggest another thing you can try.
I did this, I found it on the geforce forum:
- Go to Nvidia Control Panel by Clicking on Your Desktop and Clicking on "NVIDIA Control Panel"
- Once in Nvidia Control Panel Click on the Tab "Manage 3D settings"
- Click on the Restore Button.
- Make sure that antialiased-FXAA if turned OFF
Once that's done
- Go to your windows search bar and search up "SystemPropertiesPerformance.exe"
- Once in SystemPropertiesPerformance.exe uncheck "Smooth edges of Screen Font" and "Use drop shadows for icons on the desktop"
RESTART YOUR PC
- Open the application that you have been having problems with. If it's fixed then you're good.
FOR PEOPLE THAT DONT LIKE THE LOOK OF TEXT NOW
- Go Back to SystemPropertiesPerformance.exe and recheck "Smooth edges of Screen Font" and "Use drop shadows for icons on the desktop"
