1901697 - [NVIDIA] Canvas - google sheets rendering blanks [gfx.canvas.accelerated = false fixes it]

Status: RESOLVED DUPLICATE of bug 1924578

(Core :: Graphics: Canvas2D, defect)

Description

[Andy Dearden]

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:126.0) Gecko/20100101 Firefox/126.0

Steps to reproduce:

I created a google sheet and edited it a bit (black text, no changes to cell fill or highlight settings etc.). I then left it and came back a couple of days later.

Firefox on Ubuntu 18.04

Actual results:

The data was there (shows in the edit bar as I scroll around) but was not visible in the spreadsheet.

Expected results:

data should be visible

There is data in cell A1, but it is not visible. As you can see there is an entry in A3, but it is invisible.

The Bugbug bot thinks this bug should belong to the 'Core::Widget: Gtk' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Note - what's really strange is that the data comes up visible as the sheet is initially loading, but then it disappears (blue on blue or something).

I've experienced this and it does not happen when hardware acceleration is disabled.

Please attach your about:support page.

Andy, can you test with HW acceleration disabled?

Thanks.

Hi Martin / Nathan

Thank you so much for taking this on.

I am not able to reproduce the bug in my current version: Firefox 129.0.1

I don't have hardware acceleration enabled ( and I've never switched that before, so presumably it was not enabled when I had the problem in 126.0

Thanks

Andy

I think this is related to canvas caching. If I set gfx.canvas.accelerated.cache-items=0 the problem stops happening even with hardware acceleration on. Seems like possibly the wrong data is being retrieved from cache causing the cells to render incorrect values.

I was able to cause glitches by creating a new spreadsheet and 10 columns in 40 rows with the letter 'A'. Then just clicking around to different cells. After enough clicks, the blue row and column indicators at the edges will start to show in the wrong place occasionally. Adjusting the cache items and cache size affects how many clicks it takes to make this happen.

The severity field is not set for this bug.
:lsalzman, could you have a look please?

This certainly lines up with my experience, where if I'm working in a sheet that has a lot of data over multiple tabs, it'll start flashing visuals from the wrong tab on the screen while things like the cell selection box will continue to appear in the right place. This affects Microsoft Excel online too. It does make working in these web apps pretty much impossible if you're in there for more than a minute or two. I can confirm your about:config tweak works around the problem too.

I'm on FF 131.0 (64 bit) - Fedora 40

Had the same issue described here and tried the following:

set gfx.canvas.accelerated.cache-items=0--> issue still occurred, less frequently

then, set gfx.webrender.software to false --> issue was resolved, BUT then video playback at high resolution or full screen became too slow (low fps)

I have since reverted gfx.webrender.software to true and I'm testing with setting gfx.canvas.accelerated to false. I'll post back in a few weeks with updates.

Does 'gfx.canvas.accelerated' work for you?

Comment 15

[Nathan Babb]

Setting gfx.canvas.accelerated = false prevents this from happening for me too.

Comment 18

[Daniel Persson]

As a layman in programming, I'm just curious.
Is this is a Nvidia driver bug, so up to them to eventually fix or is this a bug with Firefox?

It's unclear so far.

Comment 20

[Kelsey Gilbert [:jgilbert]]

It seems important to figure out though, especially since we are seeing duplicates of this issue.

Comment 21

[Henry]

After 2 weeks of continuous use o Google Sheets and Docs, I can confirm that setting gfx.canvas.accelerated = false solves the issue.
