Could not reproduce this with Blender hash 21cb6f09ffa8 on macOS 10.15.6 and Intel HD Graphics 4000

Seen a similar problem with mesa 20.04, it got fixed with mesa 20.07 and up

Adding the ability to use bold and italics is nice, but probably we should add this properly using real font variants rather than generated variations, which are almost always a lot worse that bespoke weights.

And if we do that, I think it might be a good time to actually review the UI font we use to begin with - it's quite an old font that has since ben bested by other, better UI fonts.

I can reproduce on Fedora 32, start Blender, Load Factory Settings and select the default cube, hide it with the "h"-key and then pressing the TAB-key, this on Blender 2.83 Beta e5ace51295b9.

With the overnight update of the Fedora 32 Mesa drivers to version 20.0.7 Blender 50ef801a79b5 no longer crashes and also the current nightly build e5ace51295b9 does not crash upon closing the Preference and File Browser windows! Many thanks Clément (and others!) for your attention, time and patience!

Blender 2.90 Alpha f9d0f59bed4d works now, did the patch make it into Blender 2.83 Beta yet? For the buildbot version 50ef801a79b5 still crashes unfortunately...

It also happens with:

Fedora 32 here... Semi rolling release...

I concur with Eric, still crashing with hash 9605c2616696 here

Worked fine before I went from Fedora 31 to Fedora 32... And the crashes only occur when closing an extra Blender window, like Preferences or the File Browser, nothing exciting there...

Continues to crash with version: 2.83 (sub 15), branch: master, commit date: 2020-05-02 11:33, hash: rB1623fdb3bc55

Additional info: Didn't have this issue under Fedora 31... And Blender 2.79 doesn't have this problem while being under Fedora 32

Problem also exists in the official Blender 2.82a release, on the same system, after having deleted the complete ~/.config/blender directory...

This on several of the machines at my disposal, both on macOS and Linux...

With the current beta 2.82 and macOS 10.15.2 Catalina I have not had the problem yet, no...

I do not think it is a bug but activating Blender its factory-setup does not go far / deep enough, it does not delete preference files. Back then Blender crashed and kept crashing, until I manually deleted the Preferences folder for Blender.

I have been running the 2.82 beta on that same machine now, which has been updated to Ubuntu 19.10 in the mean time. So not an issue at this moment, no.

In the mean time I have updated / upgraded to Fedora 31 and with the current build from December 30th 2019, switching to fullscreen and back presents no problems.

This morning I downloaded the most recent Daily Build, version rB0812949bbc3d and found that it had the exact same problem. I tried launching it using the Terminal with a --factory-setup, still crashed right upon launching.

Goedemorgen Jeroen,

Here are some of the requested info-files, all created on the same machine, just switching between Fedora 30, where the Window Fullscreen causes a crash upon returning and Ubuntu 19.04, where it works like a charm... :

Unable to reproduce on macOS 10.14.5, MacBook Pro Mid 2012, Intel HD Graphics 4000, works fine with everything accessible.

Is there anything I can do to test that? It is not a machine with a real GPU, just an Intel HD 4000.

The earlier Ubuntu test was on another machine running 18.04.2LTS, but for completeness, I just formatted the machine running Fedora 30 and installed Ubuntu 19.04 on it, Blender its "Toggle Window Fullscreen" performed flawlessly.

I grab Blender 2.80 beta daily and yes, three or four version back it worked fine.

Are your popup menus and drop down menus from the menu bar transparent by any chance...? Then it could be related to UI graphics glitches on macOS with Intel HD 4000...?

It's made a bit more complicated by the fact that de0cae29cf751 added additional fixes on this commit, so 77f5210f2233 by itself is already known to be wrong, it's the combined change that needs to be debugged.

This is the exact same problem as T65383, where a "Load Factory Settings" unfortunately doesn't change things. On a cleanly installed macOS machine with just Buildbot daily Blender 2.80 beta's installed.

Here you go:

On Blender 2.80 (sub 72) things were fine, didn't download sub 73, so can't tell when the UI artifacts got introduced. Nothing else changed on the machine except for a newer daily build of Blender.

Then I get this:

Tried the same buildbot version on another machine under Ubuntu 18.04.2 LTS and there the UI artifacts don't appear, just the macOS version (10.14.5)

That would be?
