element-desktop 1.11.35 broken due to shader compilation issues

[joepie91]

Describe the bug

When starting element-desktop, the tray icon remains blank, and the only things that render in the window are the background color and the cursor (if the input field is active). Rebooting did not fix this. Issue seems to occur since last night's update, though I'm not certain if that's related.

Steps To Reproduce

Steps to reproduce the behavior:

1. Install and start element-desktop
2. Observe brokenness

Expected behavior

It should work :)

Screenshots

Starting it from a terminal yields hundreds if not thousands of copies of this error:

I'm running amdgpu drivers on an RX 5700XT, and my desktop environment is Plasma under (to my knowledge) X11. Issue occurs when element-desktop is installed from either stable or unstable.

1.11.35 was working before my rebuild today, so something has clearly regressed between f240619 and faa1bc7. I live on master/unstable.

I also noticed that the font size on my terminal is much smaller since the update.

I'm also on an RX 5700XT with amdgpu drivers, but on Sway.

After talking to a few others, known workarounds so far (pick one):

• rm -rf ~/.config/Element/GPUCache
• Disable GPU: Element not Rendering Graphics element-hq/element-desktop#1029 (comment)

Related issue: element-hq/element-desktop#1029

~/.config/Element/GPUCache

config … cache … config … cache … config … cache 🤦

[mweinelt]

So this must be the mesa 22.1.3 update then and pruning the now incompatible shader cache is probably the best way forward.

Logseq also suffers from this, I reported this upstream. logseq/logseq#10031
It could make sense though to escalate this to the electron level, to make that runtime handle such conditions automatically.

Note: the cache was in ~/.config/Riot/GPUCache in my case. That's probably when you have been using Element from the earlier days
