Created attachment 1282524 [details] A video showing the bug Description of problem: When running eclipse for a while, it suddently starts to re-render some tabs all the time for no reason. This causes noticable load. Version-Release number of selected component (if applicable): eclipse-swt-4.6.3-3.fc26.x86_64 eclipse-pydev-5.5.0-3.fc26.x86_64 gtk3-3.22.15-1.fc26.x86_64 How reproducible: often, after Eclipse has been running and used for a while, almost always after ca. 1 hour. Steps to Reproduce: Unclear. Run eclipse for a while. Actual results: Tabs start flickering and changing its size and font face (regular vs. italic) all the time. This causes noticable CPU load and makes the whole desktop session sluggish. Expected results: Don't change tabs rendering. Additional info: This issue might be related to the eclipse-pydev plugin, which is in bad state.
Would you please try with fully uptodate F26? We are shipping 4.7 in F26 and I want to be sure that it's not some issue that is already fixed.
Ooops, sorry we haven't done that yet but it would be nice if you can try in rawhide VM. I can not reproduce it myself.

My F26 is fully updated. (In reply to Alexander Kurtakov from comment #2) > Ooops, sorry we haven't done that yet but it would be nice if you can try in > rawhide VM. I can not reproduce it myself. I can't do that now, will take a few days until I can test on rawhide VM. Would Oxygen M7 from https://www.eclipse.org/downloads/index-developer.php be enough to test? That's way easier for me than setting up a VM and putting all my potentially relevant stuff in there.

Hm, on 4.7 RC1 I cannot reproduce this exact bug any more. The GUI still feels sluggish though.

Is there any plan to get Eclipse 4.7 into Fedora 26 repos after the final release?

Hi Christian, Now that Eclipse 4.7 Oxygen is available in F26, does this alleviate your problem at all?
