blank (unrendered) window after the most recent update (1.84.2)

[toudi]

Describe the bug
After updating vscodium to the most recent version (1.84.2, release 23317) I realized that I could no longer see anything inside the window unless I start vscodium with --disable-gpu switch

Please confirm that this problem is VSCodium-specific

• This bug doesn't happen if I use Microsoft's Visual Studio Code. It only happens in VSCodium.
• Visual Studio Code version checked: 1.84.2, commit starts with 1a5daa

Please confirm that the issue/resolution isn't already documented

• I checked the Docs page and the Troubleshooting page and my issue is not mentioned there.

To Reproduce
Steps to reproduce the behavior:

1. Launch VSCodium
2. You can see that the cursor changes it's shape sometimes but you cannot see anything

Expected behavior
Icons and components are rendered inside the GUI

Screenshots
codium - default parameters. when I move the cursor to the left (where there usually is a file picker) I can see the cursor change shape to "hand"

codium - launched with --disable-gpu switch

visual studio code (default parameters)

Desktop (please complete the following information):

• OS: OpenSUSE Tumbleweed
• Architecture x64
• Version [e.g. 1.84.2 # 23317]
• App Manager zypper
• Sandboxed no

Additional context
I am using a ryzen CPU:

model name	: AMD Ryzen 5 5600G with Radeon Graphics

when I launch VSCodium with verbose flag here's a fragment of what I can see in the terminal codium --verbose:

sadly, I have no idea whether this is relevant or does it usually happen. theoretically it is relevant given that it's about OpenGL and I cannot see any output being rendered so I thought I'd attach it as well

hmm just realized that it is related to PR #1699 . I've removed the cache directory and vscodium is working again. Feel free to close this bug report if you want
