GNOME 3.20 After the update...

Updated today and there were some mishaps. I looked on the forum and it seems I'm not alone. I was wondering if we want to have a general thread about the issues and workarounds so that people can look into one place. If that sound like plan, here's my issue(s):

I am running on a HiDPI screen and after the update the scaling was a bit weird here and there. I had to update the GTK scaling manually and for some reason there's still some inconsistencies. For example, my cursor would turn really small when I hover over the task bar and while in gnome-shell menu. That can be fixed by making GTK scale x2, but then some apps look really big - Gnome's 2048 for instance. Qt and Gnome itself seem to be unaffected by this. I wonder what people's experience has been on this.

For now I have a file /etc/profile.d/qt-hidpi.sh:

## New Qt apps use this
export QT_AUTO_SCREEN_SCALE_FACTOR=1

## Does not work
# export QT_SCALE_FACTOR=2

## Manually set for older Qt, set only if needed
# export QT_DEVICE_PIXEL_RATIO=2

## Scale GDK
export GDK_SCALE=2

## Makes text too small
# export GDK_DPI_SCALE=0.5

Is this under X or Wayland?

I don't really know what I'm doing.

X server. I tried Wayland, but I get stutters. But Wayland has never been stable for me anyway.

I have the same issue with the cursor getting small hovering over the task bar and in gnome-shell menu... weird!

It doesn't happen in Wayland: I guess it's time for me to test it again for a while

Re: GNOME 3.20 After the update...

So I switched to Wayland for a while. Although it seems stable (no glitches) it eats up tons of cpu under some circumstances like scrolling some text in gedit (strace says that a lot of time is spent on futex).

Coming back to Xorg I noted that as soon as I open a gnome-terminal, the cursor size stabilizes...

Re: GNOME 3.20 After the update...

I got the same problem: on startup of the DE I get a cursor changing size depending the region (gnome-shell bar, desktop, left bar, ...). I fix by himself opening gnome-terminal or restarting gnome-shell (ALT-F2 + r + enter).

On startup I often get a white background on the desktop. A 'nautilus -q ; nautilus' fixes the problem. It looks a race-condition on startup on the DE services.

I think I have a similar problem in that the background is not showing (it's gray) -- only if I turn desktop icons off, I get the background back. If anyone knows if this is a bug or a new behaviour, it would be helpful to know.

Still unsolved. I had a new update yesterday which also broke the click-on-tapping of my touchpad.

Maybe I should wipe out my Gnome config and let it rebuild it from scratch...

looks like  your theme is not compatible with 3.20, try with adwaita, or vertex theme from git to see if your problem persits with those themes

have you tried logging in with a new user? 

i have detected no issues using gnome 3.20 by now, except from one thing, it occurs every few days and lasts only 1-3 seconds:  at a random positon and size a rectangular part of my screen flickers.

i suspect it might be related to conky since i didnt see such a thing before running conky.

Re: GNOME 3.20 After the update...

Just want to let people in this post know that you are not alone! Same issue here. Tried login with a fresh new user with no luck.

I advocate that OP post any link to bug reports (if there are any) so that we can reconfirm the issue and push people to solve it.

Re: GNOME 3.20 After the update...

Just for log here, from my side on my laptop, using a standard screen resolution of 1920x1080 on a 13.3" - 16:9 - I got issue with huge widgets & fonts under gnome-shell 3.20.x and QT apps. (not KDE ones)
I fixed it today with these settings :

/etc/profile.d/qt-hidpi.sh

export QT_STYLE_OVERRIDE=adwaita
export QT_AUTO_SCREEN_SCALE_FACTOR=0.8
