Hi,

I just downloaded last version of anki from ankiweb. I installed it again. I started with shift to avoid loading any add-on.
Parts of all windows are missing, as shown in the screenshot.
I am on ubuntu, with everything up to date. Normally, I’ve everything needed to compile anki, even if it should not be relevant here.

@ArthurMilchior

Does changing the hardware acceleration option in the preferences help? Does the -alternate download behave differently?

#3

I just tried to turn hardware acceleration off, and it does not solve the problem.

#4

Can you try installing older alphas/betas/stable builds until it start working again?

You can also try changing a few things like: (one at a time): https://changes.ankiweb.net/#/known-issues

  1. ANKI_NOHIGHDPI=1
  2. ANKI_WEBSCALE=1.1
  3. ANKI_WEBSCALE=1
  4. ANKI_WEBSCALE=0.9
  5. echo auto > %APPDATA%\Anki2\gldriver
  6. echo angle > %APPDATA%\Anki2\gldriver
  7. echo software > %APPDATA%\Anki2\gldriver
#5

FYI, angle only works on Windows, and auto/software is what is toggled by the hardware acceleration checkbox. The others are worth trying though.

#6

Current master shows the message "Error loading ‘auto’ graphics driver. Please start Anki again to try next driver. " when I’m trying to run it

#7

I’m trying to checkout older version and do “make run”. But even on 2.1.25 I know have the same message occurring. I don’t get it

#8

I can install the alternate version. However, I can not open the collection; I get the message

Traceback (most recent call last):

I have clicked on “downgrad” when I closed from master

I tried downloading from .25 to 2.1.21 from github’s release (it’s not on your https://apps.ankiweb.net/downloads/archive/ page ) and doing sudo make install. Each time I had the same problem of missing buttons

@addons_zz where do you want me to put ANKI_NOHIGHDPI=1 ?

#9

If you read the reference link I gave on my post https://changes.ankiweb.net/#/known-issues you will know. It is a environment variable you export before running Anki. Usually, you open a command line, run export ANKI_NOHIGHDPI=1 and run Anki on the same terminal.

#10

That implies you ran the new version again after downgrading, or something went wrong with the downgrade. The latter should have produced an error in that case however.

#11

Thanks. I only saw indication about how to change this in windows

#12

I opened another collection on 2.1.15, and it worked.

I installed 2.1.25 again in order to downgrade the buggy collection. And then I discovered that it just work again, normally, I have all buttons and everything. Didn’t even need to export an environment variable.
I have no idea what is going on here. I fear that it will eventually break again. But at least, data are saved in this forum for potential future investigation

#13

Using export ANKI_NOHIGHDPI=1 works still. Turning off devices acceleration worked. Hopefully this will be fixed in the future?
